====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Reinstantiate Florian Westphal as a Netfilter maintainer.

2) Depend on both NETFILTER_XTABLES and NETFILTER_XTABLES_LEGACY,
   from Arnd Bergmann.

3) Use id to annotate last conntrack/expectation visited to resume
   netlink dump, patches from Florian Westphal.

4) Fix bogus element in nft_pipapo avx2 lookup, introduced in
   the last nf-next batch of updates, also from Florian.

5) Return 0 instead of recycling ret variable in
   nf_conntrack_log_invalid_sysctl(), introduced in the last
   nf-next batch of updates, from Dan Carpenter.

6) Fix WARN_ON_ONCE triggered by syzbot with larger cgroup level
   in nft_socket.

* tag 'nf-25-08-07' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf:

e8214ed59b VFIO updates for v6.17-rc1 v2 
- Fix imbalance where the no-iommu/cdev device path skips too much
    on open, failing to increment a reference, but still decrements
    the reference on close.  Add bounds checking to prevent such
    underflows. (Jacob Pan)
 
  - Fill missing detach_ioas op for pds_vfio_pci, fixing probe failure
    when used with IOMMUFD. (Brett Creeley)
 
  - Split SR-IOV VFs to separate dev_set, avoiding unnecessary
    serialization between VFs that appear on the same bus.
    (Alex Williamson)
 
  - Fix a theoretical integer overflow is the mlx5-vfio-pci variant
    driver. (Artem Sadovnikov)
 
  - Implement missing VF token checking support via vfio cdev/IOMMUFD
    interface. (Jason Gunthorpe)
 
  - Update QAT vfio-pci variant driver to claim latest VF devices.
    (Małgorzata Mielnik)
 
  - Add a cond_resched() call to avoid holding the CPU too long during
    DMA mapping operations. (Keith Busch)

Pull VFIO updates from Alex Williamson:

 - Fix imbalance where the no-iommu/cdev device path skips too much on
   open, failing to increment a reference, but still decrements the
   reference on close. Add bounds checking to prevent such underflows
   (Jacob Pan)

 - Fill missing detach_ioas op for pds_vfio_pci, fixing probe failure
   when used with IOMMUFD (Brett Creeley)

 - Split SR-IOV VFs to separate dev_set, avoiding unnecessary
   serialization between VFs that appear on the same bus (Alex
   Williamson)

 - Fix a theoretical integer overflow is the mlx5-vfio-pci variant
   driver (Artem Sadovnikov)

 - Implement missing VF token checking support via vfio cdev/IOMMUFD
   interface (Jason Gunthorpe)

 - Update QAT vfio-pci variant driver to claim latest VF devices
   (Małgorzata Mielnik)

 - Add a cond_resched() call to avoid holding the CPU too long during
   DMA mapping operations (Keith Busch)

8d6841d5cb MAINTAINERS: hand over Kbuild maintenance 
I'm stepping down as the maintainer of Kbuild/Kconfig.
It was enjoyable to refactor and improve the kernel build system,
but due to personal reasons, I believe it's difficult for me to
continue in this role any further.

I discussed this off-list with Nathan and Nicolas, and they have
kindly agreed to take over the maintenance of Kbuild with Odd Fixes.
I'm grateful to them for stepping in.

As for Kconfig, there are currently no designated reviewers, so the
maintainer position will remain vacant for now. I hope someone will
step up to take on the role.

 - The 5 patch series "kdump: crashkernel reservation from CMA" from Jiri
   Bohac switches us from static preallocation of the kdump crashkernel's
   working memory over to dynamic allocation.  So the difficulty of
   a-priori estimation of the second kernel's needs is removed and the
   first kernel obtains extra memory.
 
 - The 5 patch series "generalize panic_print's dump function to be used
   by other kernel parts" from Feng Tang implements some consolidation and
   rationalizatio of the various ways in which a faiing kernel splats

Toolchain and infrastructure:
 
  - Enable a set of Clippy lints: 'ptr_as_ptr', 'ptr_cast_constness',
    'as_ptr_cast_mut', 'as_underscore', 'cast_lossless' and 'ref_as_ptr'.
 
    These are intended to avoid type casts with the 'as' operator, which
    are quite powerful, into restricted variants that are less powerful
    and thus should help to avoid mistakes.
 
  - Remove the 'author' key now that most instances were moved to the
    plural one in the previous cycle.
 
 'kernel' crate:
 
  - New 'bug' module: add 'warn_on!' macro which reuses the existing
    'BUG'/'WARN' infrastructure, i.e. it respects the usual sysctls and
    kernel parameters:
 
        warn_on!(value == 42);
 
    To avoid duplicating the assembly code, the same strategy is followed
    as for the static branch code in order to share the assembly between
    both C and Rust. This required a few rearrangements on C arch headers
    -- the existing C macros should still generate the same outputs, thus
    no functional change expected there.
 
  - 'workqueue' module: add delayed work items, including a 'DelayedWork'
    struct, a 'impl_has_delayed_work!' macro and an 'enqueue_delayed'
    method, e.g.:
 
        /// Enqueue the struct for execution on the system workqueue,
        /// where its value will be printed 42 jiffies later.
        fn print_later(value: Arc<MyStruct>) {
            let _ = workqueue::system().enqueue_delayed(value, 42);
        }
 
  - New 'bits' module: add support for 'bit' and 'genmask' functions,
    with runtime- and compile-time variants, e.g.:
 
        static_assert!(0b00010000 == bit_u8(4));
        static_assert!(0b00011110 == genmask_u8(1..=4));
 
        assert!(checked_bit_u32(u32::BITS).is_none());
 
  - 'uaccess' module: add 'UserSliceReader::strcpy_into_buf', which reads
    NUL-terminated strings from userspace into a '&CStr'.
 
    Introduce 'UserPtr' newtype, similar in purpose to '__user' in C, to
    minimize mistakes handling userspace pointers, including mixing them
    up with integers and leaking them via the 'Debug' trait. Add it to
    the prelude, too.
 
  - Start preparations for the replacement of our custom 'CStr' type
    with the analogous type in the 'core' standard library. This will
    take place across several cycles to make it easier. For this one,
    it includes a new 'fmt' module, using upstream method names and some
    other cleanups.
 
    Replace 'fmt!' with a re-export, which helps Clippy lint properly,
    and clean up the found 'uninlined-format-args' instances.
 
  - 'dma' module:
 
    - Clarify wording and be consistent in 'coherent' nomenclature.
 
    - Convert the 'read!()' and 'write!()' macros to return a 'Result'.
 
    - Add 'as_slice()', 'write()' methods in 'CoherentAllocation'.
 
    - Expose 'count()' and 'size()' in 'CoherentAllocation' and add the
      corresponding type invariants.
 
    - Implement 'CoherentAllocation::dma_handle_with_offset()'.
 
  - 'time' module:
 
    - Make 'Instant' generic over clock source. This allows the compiler
      to assert that arithmetic expressions involving the 'Instant' use
      'Instants' based on the same clock source.
 
    - Make 'HrTimer' generic over the timer mode. 'HrTimer' timers take a
      'Duration' or an 'Instant' when setting the expiry time, depending
      on the timer mode. With this change, the compiler can check the
      type matches the timer mode.
 
    - Add an abstraction for 'fsleep'. 'fsleep' is a flexible sleep
      function that will select an appropriate sleep method depending on
      the requested sleep time.
 
    - Avoid 64-bit divisions on 32-bit hardware when calculating
      timestamps.
 
    - Seal the 'HrTimerMode' trait. This prevents users of the
      'HrTimerMode' from implementing the trait on their own types.
 
    - Pass the correct timer mode ID to 'hrtimer_start_range_ns()'.
 
  - 'list' module: remove 'OFFSET' constants, allowing to remove pointer
    arithmetic; now 'impl_list_item!' invokes 'impl_has_list_links!' or
    'impl_has_list_links_self_ptr!'. Other simplifications too.
 
  - 'types' module: remove 'ForeignOwnable::PointedTo' in favor of a
    constant, which avoids exposing the type of the opaque pointer, and
    require 'into_foreign' to return non-null.
 
    Remove the 'Either<L, R>' type as well. It is unused, and we want to
    encourage the use of custom enums for concrete use cases.
 
  - 'sync' module: implement 'Borrow' and 'BorrowMut' for 'Arc' types
    to allow them to be used in generic APIs.
 
  - 'alloc' module: implement 'Borrow' and 'BorrowMut' for 'Box<T, A>';
     and 'Borrow', 'BorrowMut' and 'Default' for 'Vec<T, A>'.
 
  - 'Opaque' type: add 'cast_from' method to perform a restricted cast
    that cannot change the inner type and use it in callers of
    'container_of!'. Rename 'raw_get' to 'cast_into' to match it.
 
  - 'rbtree' module: add 'is_empty' method.
 
  - 'sync' module: new 'aref' submodule to hold 'AlwaysRefCounted' and
    'ARef', which are moved from the too general 'types' module which we
    want to reduce or eventually remove. Also fix a safety comment in
    'static_lock_class'.
 
 'pin-init' crate:
 
  - Add 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are now
    (pin-)initializers.
 
  - Add 'Zeroable::init_zeroed()' that delegates to 'init_zeroed()'.
 
  - New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
    it via 'Zeroable::zeroed()'.
 
  - Implement 'Zeroable' for 'Option<&T>', 'Option<&mut T>' and for
    'Option<[unsafe] [extern "abi"] fn(...args...) -> ret>' for '"Rust"'
    and '"C"' ABIs and up to 20 arguments.
 
  - Changed blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
    [Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'.
 
  - Renamed 'zeroed()' to 'init_zeroed()'.
 
  - Upstream dev news: improve CI more to deny warnings, use
    '--all-targets'. Check the synchronization status of the two '-next'
    branches in upstream and the kernel.
 
 MAINTAINERS:
 
  - Add Vlastimil Babka, Liam R. Howlett, Uladzislau Rezki and Lorenzo
    Stoakes as reviewers (thanks everyone).
 
 And a few other cleanups and improvements.

186f3edfdd Pin control changes for v6.17 
Core changes:
 
 - Open code PINCTRL_FUNCTION_DESC() instead of defining
   a complex macro only used in one place.
 
 - Add pinmux_generic_add_pinfunction() helper and
   use this in a few drivers.
 
 New drivers:
 
 - Amlogic S7, S7D and S6 pin control support.
 
 - Eswin EIC7700 pin control support.
 
 - Qualcomm PMIV0104, PM7550 and Milos pin control
   support.
 
   Because of unhelpful numbering schemes, the Qualcomm
   driver now needs to start to rely on SoC codenames.
 
 - STM32 HDP pin control support.
 
 - Mediatek MT8189 pin control support.
 
 Improvements:
 
 - Switch remaining pin control drivers over to the
   new GPIO set callback that provides a return value.
 
 - Support RSVD (reserved) pins in the STM32 driver.
 
 - Move many fixed assignments over to pinctrl_desc
   definitions.
 
 - Handle multiple TLMM regions in the Qualcomm driver.

b753522bed kho: add test for kexec handover 
Testing kexec handover requires a kernel driver that will generate some
data and preserve it with KHO on the first boot and then restore that data
and verify it was preserved properly after kexec.

To facilitate such test, along with the kernel driver responsible for data
generation, preservation and restoration add a script that runs a kernel
in a VM with a minimal /init.  The /init enables KHO, loads a kernel image
for kexec and runs kexec reboot.  After the boot of the kexeced kernel,
the driver verifies that the data was properly preserved.

1f03d55e5e MAINTAINERS: add maintainers for delaytop 
The delaytop tool supports showing system delays and task-level delays,
effectively identifying the top-n tasks with high latency in the system,
which is highly beneficial for improving system performance.  Wang Yaxin
and her colleague Fan Yu focus on locating system delay issues.  To
promote the thriving development of delaytop, we hope to serve as
maintainers to continuously improve it, aiming to provide a more effective
solution for system latency issues in the future.

Merge tag 'pci-v6.17-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Allow built-in drivers, not just modular drivers, to use async
     initial probing (Lukas Wunner)

   - Support Immediate Readiness even on devices with no PM Capability
     (Sean Christopherson)

   - Consolidate definition of PCIE_RESET_CONFIG_WAIT_MS (100ms), the
     required delay between a reset and sending config requests to a
     device (Niklas Cassel)

   - Add pci_is_display() to check for "Display" base class and use it
     in ALSA hda, vfio, vga_switcheroo, vt-d (Mario Limonciello)

   - Allow 'isolated PCI functions' (multi-function devices without a
     function 0) for LoongArch, similar to s390 and jailhouse (Huacai
     Chen)

  Power control:

   - Add ability to enable optional slot clock for cases where the PCIe
     host controller and the slot are supplied by different clocks
     (Marek Vasut)

  PCIe native device hotplug:

   - Fix runtime PM ref imbalance on Hot-Plug Capable ports caused by
     misinterpreting a config read failure after a device has been
     removed (Lukas Wunner)

   - Avoid creating a useless PCIe port service device for pciehp if the
     slot is handled by the ACPI hotplug driver (Lukas Wunner)

   - Ignore ACPI hotplug slots when calculating depth of pciehp hotplug
     ports (Lukas Wunner)

  Virtualization:

   - Save VF resizable BAR state and restore it after reset (Michał
     Winiarski)

   - Allow IOV resources (VF BARs) to be resized (Michał Winiarski)

   - Add pci_iov_vf_bar_set_size() so drivers can control VF BAR size
     (Michał Winiarski)

  Endpoint framework:

   - Add RC-to-EP doorbell support using platform MSI controller,
     including a test case (Frank Li)

   - Allow BAR assignment via configfs so platforms have flexibility in
     determining BAR usage (Jerome Brunet)

  Native PCIe controller drivers:

   - Convert amazon,al-alpine-v[23]-pcie, apm,xgene-pcie,
     axis,artpec6-pcie, marvell,armada-3700-pcie, st,spear1340-pcie to
     DT schema format (Rob Herring)

   - Use dev_fwnode() instead of of_fwnode_handle() to remove OF
     dependency in altera (fixes an unused variable), designware-host,
     mediatek, mediatek-gen3, mobiveil, plda, xilinx, xilinx-dma,
     xilinx-nwl (Jiri Slaby, Arnd Bergmann)

   - Convert aardvark, altera, brcmstb, designware-host, iproc,
     mediatek, mediatek-gen3, mobiveil, plda, rcar-host, vmd, xilinx,
     xilinx-dma, xilinx-nwl from using pci_msi_create_irq_domain() to
     using msi_create_parent_irq_domain() instead; this makes the
     interrupt controller per-PCI device, allows dynamic allocation of
     vectors after initialization, and allows support of IMS (Nam Cao)

  APM X-Gene PCIe controller driver:

   - Rewrite MSI handling to MSI CPU affinity, drop useless CPU hotplug
     bits, use device-managed memory allocations, and clean things up
     (Marc Zyngier)

   - Probe xgene-msi as a standard platform driver rather than a
     subsys_initcall (Marc Zyngier)

  Broadcom STB PCIe controller driver:

   - Add optional DT 'num-lanes' property and if present, use it to
     override the Maximum Link Width advertised in Link Capabilities
     (Jim Quinlan)

  Cadence PCIe controller driver:

   - Use PCIe Message routing types from the PCI core rather than
     defining private ones (Hans Zhang)

  Freescale i.MX6 PCIe controller driver:

   - Add IMX8MQ_EP third 64-bit BAR in epc_features (Richard Zhu)

   - Add IMX8MM_EP and IMX8MP_EP fixed 256-byte BAR 4 in epc_features
     (Richard Zhu)

   - Configure LUT for MSI/IOMMU in Endpoint mode so Root Complex can
     trigger doorbel on Endpoint (Frank Li)

   - Remove apps_reset (LTSSM_EN) from
     imx_pcie_{assert,deassert}_core_reset(), which fixes a hotplug
     regression on i.MX8MM (Richard Zhu)

   - Delay Endpoint link start until configfs 'start' written (Richard
     Zhu)

  Intel VMD host bridge driver:

   - Add Intel Panther Lake (PTL)-H/P/U Vendor ID (George D Sworo)

  Qualcomm PCIe controller driver:

   - Add DT binding and driver support for SA8255p, which supports ECAM
     for Configuration Space access (Mayank Rana)

   - Update DT binding and driver to describe PHYs and per-Root Port
     resets in a Root Port stanza and deprecate describing them in the
     host bridge; this makes it possible to support multiple Root Ports
     in the future (Krishna Chaitanya Chundru)

   - Add Qualcomm QCS615 to SM8150 DT binding (Ziyue Zhang)

   - Add Qualcomm QCS8300 to SA8775p DT binding (Ziyue Zhang)

   - Drop TBU and ref clocks from Qualcomm SM8150 and SC8180x DT
     bindings (Konrad Dybcio)

   - Document 'link_down' reset in Qualcomm SA8775P DT binding (Ziyue
     Zhang)

   - Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
     (Niklas Cassel)

  Rockchip PCIe controller driver:

   - Drop unused PCIe Message routing and code definitions (Hans Zhang)

   - Remove several unused header includes (Hans Zhang)

   - Use standard PCIe config register definitions instead of
     rockchip-specific redefinitions (Geraldo Nascimento)

   - Set Target Link Speed to 5.0 GT/s before retraining so we have a
     chance to train at a higher speed (Geraldo Nascimento)

  Rockchip DesignWare PCIe controller driver:

   - Prevent race between link training and register update via DBI by
     inhibiting link training after hot reset and link down (Wilfred
     Mallawa)

   - Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
     (Niklas Cassel)

  Sophgo PCIe controller driver:

   - Add DT binding and driver for Sophgo SG2044 PCIe controller driver
     in Root Complex mode (Inochi Amaoto)

  Synopsys DesignWare PCIe controller driver:

   - Add required PCIE_RESET_CONFIG_WAIT_MS after waiting for Link up on
     Ports that support > 5.0 GT/s. Slower Ports still rely on the
     not-quite-correct PCIE_LINK_WAIT_SLEEP_MS 90ms default delay while
     waiting for the Link (Niklas Cassel)"

c6439bfaab Deferred unwind changes for 6.17 
This is the core infrastructure for the deferred unwinder that is required
 for sframes[1]. Several other patch series is based on this work although
 those patch series are not dependent on each other. In order to simplify the
 development, having this core series upstream will allow the other series to
 be worked on in parallel. The other series are:
 
 - The two patches to implement x86:
   https://lore.kernel.org/linux-trace-kernel/20250717004958.260781923@kernel.org/
   https://lore.kernel.org/linux-trace-kernel/20250717004958.432327787@kernel.org/
 
 - The s390 work:
   https://lore.kernel.org/linux-trace-kernel/20250710163522.3195293-1-jremus@linux.ibm.com/
 
 - The perf work:
   https://lore.kernel.org/linux-trace-kernel/20250718164119.089692174@kernel.org/
 
 - The ftrace work:
   https://lore.kernel.org/linux-trace-kernel/20250424192612.505622711@goodmis.org/
 
 - The sframe work:
   https://lore.kernel.org/linux-trace-kernel/20250717012848.927473176@kernel.org/
 
 And more is on the way.
 
 The core infrastructure adds the following in kernel APIs:
 
 - int unwind_user_faultable(struct unwind_stacktrace *trace);
 
     Performs a user space stack trace that may fault user pages in.
 
 - int unwind_deferred_init(struct unwind_work *work, unwind_callback_t func);
 
     Allows a tracer to register with the unwind deferred infrastructure.
 
 - int unwind_deferred_request(struct unwind_work *work, u64 *cookie);
 
     Used when a tracer request a deferred trace. Can be called from interrupt
     or NMI context.
 
 - void unwind_deferred_cancel(struct unwind_work *work);
 
     Called by a tracer to unregister from the deferred unwind infrastructure.
 
 - void unwind_deferred_task_exit(struct task_struct *task);
 
     Called by task exit code to flush any pending unwind requests.
 
 - void unwind_task_init(struct task_struct *task);
 
     Called by do_fork() to initialize the task struct for the deferred
     unwinder.
 
 - void unwind_task_free(struct task_struct *task);
 
     Called by do_exit() to free up any resources used by the deferred
     unwinder.
 
 None of the above is actually compiled unless an architecture enables it,
 which none currently do.

   creates a standalone notifier for NUMA node memory state changes.
   Previously these were lumped under the more general memory on/offline
   notifier.

   cleans up the pageblock isolation code and fixes a potential issue which
   doesn't seem to cause any problems in practice.
 
 - The 5 patch series "selftests/damon: add python and drgn based DAMON
   sysfs functionality tests" from SeongJae Park adds additional drgn- and
   python-based DAMON selftests which are more comprehensive than the
   existing selftest suite.

   monitoring intervals and DAMOS quota" from SeongJae Park adds some
   tracepoints to some DAMON auto-tuning code.
 
 - The 6 patch series "mm/damon: fix misc bugs in DAMON modules" from
   SeongJae Park does that.
 
 - The 6 patch series "mm/damon: misc cleanups" from SeongJae Park also
   does what it claims.
 
 - The 4 patch series "mm: folio_pte_batch() improvements" from David
   Hildenbrand cleans up the large folio PTE batching code.

   migrate_{hot,cold} actions" from SeongJae Park facilitates dynamic
   alteration of DAMON's inter-node allocation policy.
 
 - The 3 patch series "Remove unmap_and_put_page()" from Vishal Moola
   provides a couple of page->folio conversions.
 
 - The 4 patch series "mm: per-node proactive reclaim" from Davidlohr
   Bueso implements a per-node control of proactive reclaim - beyond the
   current memcg-based implementation.
 
 - The 14 patch series "mm/damon: remove damon_callback" from SeongJae
   Park replaces the damon_callback interface with a more general and
   powerful damon_call()+damos_walk() interface.
 
 - The 10 patch series "mm/mremap: permit mremap() move of multiple VMAs"
   from Lorenzo Stoakes implements a number of mremap cleanups (of course)
   in preparation for adding new mremap() functionality: newly permit the
   remapping of multiple VMAs when the user is specifying MREMAP_FIXED.  It
   still excludes some specialized situations where this cannot be
   performed reliably.
 
 - The 3 patch series "drop hugetlb_free_pgd_range()" from Anthony Yznaga
   switches some sparc hugetlb code over to the generic version and removes
   the thus-unneeded hugetlb_free_pgd_range().
 
 - The 4 patch series "mm/damon/sysfs: support periodic and automated
   stats update" from SeongJae Park augments the present
   userspace-requested update of DAMON sysfs monitoring files.  Automatic
   update is now provided, along with a tunable to control the update
   interval.
 
 - The 4 patch series "Some randome fixes and cleanups to swapfile" from
   Kemeng Shi does what is claims.
 
 - The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino
   and David Hildenbrand provides (and uses) a means by which debug-style
   functions can grab a copy of a pageframe and inspect it locklessly
   without tripping over the races inherent in operating on the live
   pageframe directly.
 
 - The 6 patch series "use per-vma locks for /proc/pid/maps reads" from
   Suren Baghdasaryan addresses the large contention issues which can be
   triggered by reads from that procfs file.  Latencies are reduced by more
   than half in some situations.  The series also introduces several new
   selftests for the /proc/pid/maps interface.
 
 - The 6 patch series "__folio_split() clean up" from Zi Yan cleans up
   __folio_split()!
 
 - The 7 patch series "Optimize mprotect() for large folios" from Dev
   Jain provides some quite large (>3x) speedups to mprotect() when dealing
   with large folios.
 
 - The 2 patch series "selftests/mm: reuse FORCE_READ to replace "asm
   volatile("" : "+r" (XXX));" and some cleanup" from wang lian does some
   cleanup work in the selftests code.
 
 - The 3 patch series "tools/testing: expand mremap testing" from Lorenzo
   Stoakes extends the mremap() selftest in several ways, including adding
   more checking of Lorenzo's recently added "permit mremap() move of
   multiple VMAs" feature.
 
 - The 22 patch series "selftests/damon/sysfs.py: test all parameters"
   from SeongJae Park extends the DAMON sysfs interface selftest so that it
   tests all possible user-requested parameters.  Rather than the present
   minimal subset.

Linus Torvalds
2d945dde7f This is the usual collection of primarily clk driver updates. The big part of 
the diff is all the new Qualcomm clk drivers added for a few SoCs they're
 working on. The other two vendors with significant work this cycle are Renesas
 and Amlogic. Renesas adds a bunch of clks to existing drivers and supports some
 new SoCs while Amlogic is starting a significant refactoring to simplify their
 code.
 
 The core framework gained a pair of helpers to get the 'struct device' or
 'struct device_node' associated with a 'struct clk_hw'. Some associated KUnit
 tests were added for these simple helpers as well. Beyond that core change
 there are lots of little fixes throughout the clk drivers for the stuff we see
 every day, wrong clk driver data that affects tree topology or supported
 frequencies, etc. They're not found until the clks are actually used by some
 consumer device driver.
 
 New Drivers:
  - Global, display, gpu, video, camera, tcsr, and rpmh clock controller for the
    Qualcomm Milos SoC
  - Camera, display, GPU, and video clock controllers for Qualcomm QCS615
  - Video clock controller driver for Qualcomm SM6350
  - Camera clock controller driver for Qualcomm SC8180X
  - I3C clocks and resets on Renesas RZ/G3E
  - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
    Renesas RZ/V2H(P) and RZ/V2N
  - SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
  - SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
  - Ethernet clocks and resets on Renesas RZ/G3E
  - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
    (R9A09G087) SoCs
  - Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
  - Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
    RZ/V2N
 
 Updates:
  - Support atomic PWMs in the PWM clk driver
  - clk_hw_get_dev() and clk_hw_get_of_node() helpers

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "This is the usual collection of primarily clk driver updates.

  The big part of the diff is all the new Qualcomm clk drivers added for
  a few SoCs they're working on. The other two vendors with significant
  work this cycle are Renesas and Amlogic. Renesas adds a bunch of clks
  to existing drivers and supports some new SoCs while Amlogic is
  starting a significant refactoring to simplify their code.

  The core framework gained a pair of helpers to get the 'struct device'
  or 'struct device_node' associated with a 'struct clk_hw'. Some
  associated KUnit tests were added for these simple helpers as well.

  Beyond that core change there are lots of little fixes throughout the
  clk drivers for the stuff we see every day, wrong clk driver data that
  affects tree topology or supported frequencies, etc. They're not found
  until the clks are actually used by some consumer device driver.

  New Drivers:
   - Global, display, gpu, video, camera, tcsr, and rpmh clock
     controller for the Qualcomm Milos SoC
   - Camera, display, GPU, and video clock controllers for Qualcomm
     QCS615
   - Video clock controller driver for Qualcomm SM6350
   - Camera clock controller driver for Qualcomm SC8180X
   - I3C clocks and resets on Renesas RZ/G3E
   - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
     Renesas RZ/V2H(P) and RZ/V2N
   - SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
   - SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
   - Ethernet clocks and resets on Renesas RZ/G3E
   - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
     (R9A09G087) SoCs
   - Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
   - Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
     RZ/V2N

  Updates:
   - Support atomic PWMs in the PWM clk driver
   - clk_hw_get_dev() and clk_hw_get_of_node() helpers
   - Replace round_rate() with determine_rate() in various clk drivers
   - Convert clk DT bindings to DT schema format for DT validation
   - Various clk driver cleanups and refactorings from static analysis
     tools and possibly real humans
   - A lot of little fixes here and there to things like clk tree

831462ff3e LEDs for for v6.17 
- Improvements & Fixes
   * A fix has been implemented in QCOM Flash to prevent incorrect register
     access when the driver is re-bound. This is solved by duplicating a static
     register array during the probe function, which prevents register addresses
     from being miscalculated after multiple binds.
   * The LP50xx driver now correctly handles the 'reg' property in device tree
     child nodes to ensure the multi_index is set correctly. This prevents
     issues where LEDs could be controlled incorrectly if the device tree nodes
     were processed in a different order. An error is returned if the reg
     property is missing or out of range.
   * A Kconfig dependency on between TPS6131x and V4L2_FLASH_LED_CLASS has been
     added to prevent a build failure when the driver is built-in and the V4L2
     flash infrastructure is a loadable module.
   * A potential buffer overflow warning in PCA955x was reported by older GCC
     versions has been fixed by using a more precise format specifier when
     creating the default LED label.
 
 - Cleanups & Refactoring
   * The MAINTAINERS file entry for the TPS6131X flash LED driver has been
     corrected to point to the correct device tree binding file name.
   * A comment in the Flash Class for the flash_timeout setter has been
     corrected to "flash timeout" from "flash duration" for accuracy.
   * The of_led_get() function is no longer exported as it has no users
     outside of its own module.
 
 - Removals
   * The commit to configure LED blink intervals for hardware offload in the
     Netdev Trigger has been reverted. This change was found to break existing
     PHY drivers by putting their LEDs into a permanent, unconditional blinking
     state.
 
 - Device Tree Bindings Updates
   * The binding for LP50xx has been updated to document that the child reg
     property is the index within the LED bank. The example was also updated to
     use correct values.
   * The JNCP5623 binding has been updated to add 0x39 as a valid I2C address,
     as it is used by the NCP5623C variant.

Linus Torvalds
63eb28bb14 ARM: 
- Host driver for GICv5, the next generation interrupt controller for
   arm64, including support for interrupt routing, MSIs, interrupt
   translation and wired interrupts.
 
 - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
   GICv5 hardware, leveraging the legacy VGIC interface.
 
 - Userspace control of the 'nASSGIcap' GICv3 feature, allowing
   userspace to disable support for SGIs w/o an active state on hardware
   that previously advertised it unconditionally.
 
 - Map supporting endpoints with cacheable memory attributes on systems
   with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
   maintenance on the address range.
 
 - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
   hypervisor to inject external aborts into an L2 VM and take traps of
   masked external aborts to the hypervisor.
 
 - Convert more system register sanitization to the config-driven
   implementation.
 
 - Fixes to the visibility of EL2 registers, namely making VGICv3 system
   registers accessible through the VGIC device instead of the ONE_REG
   vCPU ioctls.
 
 - Various cleanups and minor fixes.
 
 LoongArch:
 
 - Add stat information for in-kernel irqchip
 
 - Add tracepoints for CPUCFG and CSR emulation exits
 
 - Enhance in-kernel irqchip emulation
 
 - Various cleanups.
 
 RISC-V:
 
 - Enable ring-based dirty memory tracking
 
 - Improve perf kvm stat to report interrupt events
 
 - Delegate illegal instruction trap to VS-mode
 
 - MMU improvements related to upcoming nested virtualization
 
 s390x
 
 - Fixes
 
 x86:
 
 - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC,
   PIC, and PIT emulation at compile time.
 
 - Share device posted IRQ code between SVM and VMX and
   harden it against bugs and runtime errors.
 
 - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1)
   instead of O(n).
 
 - For MMIO stale data mitigation, track whether or not a vCPU has access to
   (host) MMIO based on whether the page tables have MMIO pfns mapped; using
   VFIO is prone to false negatives
 
 - Rework the MSR interception code so that the SVM and VMX APIs are more or
   less identical.
 
 - Recalculate all MSR intercepts from scratch on MSR filter changes,
   instead of maintaining shadow bitmaps.
 
 - Advertise support for LKGS (Load Kernel GS base), a new instruction
   that's loosely related to FRED, but is supported and enumerated
   independently.
 
 - Fix a user-triggerable WARN that syzkaller found by setting the vCPU
   in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU
   into VMX Root Mode (post-VMXON).  Trying to detect every possible path
   leading to architecturally forbidden states is hard and even risks
   breaking userspace (if it goes from valid to valid state but passes
   through invalid states), so just wait until KVM_RUN to detect that
   the vCPU state isn't allowed.
 
 - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of
   APERF/MPERF reads, so that a "properly" configured VM can access
   APERF/MPERF.  This has many caveats (APERF/MPERF cannot be zeroed
   on vCPU creation or saved/restored on suspend and resume, or preserved
   over thread migration let alone VM migration) but can be useful whenever
   you're interested in letting Linux guests see the effective physical CPU
   frequency in /proc/cpuinfo.
 
 - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been
   created, as there's no known use case for changing the default
   frequency for other VM types and it goes counter to the very reason
   why the ioctl was added to the vm file descriptor.  And also, there
   would be no way to make it work for confidential VMs with a "secure"
   TSC, so kill two birds with one stone.
 
 - Dynamically allocation the shadow MMU's hashed page list, and defer
   allocating the hashed list until it's actually needed (the TDP MMU
   doesn't use the list).
 
 - Extract many of KVM's helpers for accessing architectural local APIC
   state to common x86 so that they can be shared by guest-side code for
   Secure AVIC.
 
 - Various cleanups and fixes.
 
 x86 (Intel):
 
 - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest.
   Failure to honor FREEZE_IN_SMM can leak host state into guests.
 
 - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to prevent
   L1 from running L2 with features that KVM doesn't support, e.g. BTF.
 
 x86 (AMD):
 
 - WARN and reject loading kvm-amd.ko instead of panicking the kernel if the
   nested SVM MSRPM offsets tracker can't handle an MSR (which is pretty
   much a static condition and therefore should never happen, but still).
 
 - Fix a variety of flaws and bugs in the AVIC device posted IRQ code.
 
 - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware
   supports) instead of rejecting vCPU creation.
 
 - Extend enable_ipiv module param support to SVM, by simply leaving
   IsRunning clear in the vCPU's physical ID table entry.
 
 - Disable IPI virtualization, via enable_ipiv, if the CPU is affected by
   erratum #1235, to allow (safely) enabling AVIC on such CPUs.
 
 - Request GA Log interrupts if and only if the target vCPU is blocking,
   i.e. only if KVM needs a notification in order to wake the vCPU.
 
 - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the
   vCPU's CPUID model.
 
 - Accept any SNP policy that is accepted by the firmware with respect to
   SMT and single-socket restrictions.  An incompatible policy doesn't put
   the kernel at risk in any way, so there's no reason for KVM to care.
 
 - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM and
   use WBNOINVD instead of WBINVD when possible for SEV cache maintenance.
 
 - When reclaiming memory from an SEV guest, only do cache flushes on CPUs
   that have ever run a vCPU for the guest, i.e. don't flush the caches for
   CPUs that can't possibly have cache lines with dirty, encrypted data.
 
 Generic:
 
 - Rework irqbypass to track/match producers and consumers via an xarray
   instead of a linked list.  Using a linked list leads to O(n^2) insertion
   times, which is hugely problematic for use cases that create large
   numbers of VMs.  Such use cases typically don't actually use irqbypass,
   but eliminating the pointless registration is a future problem to
   solve as it likely requires new uAPI.
 
 - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *",
   to avoid making a simple concept unnecessarily difficult to understand.
 
 - Decouple device posted IRQs from VFIO device assignment, as binding a VM
   to a VFIO group is not a requirement for enabling device posted IRQs.
 
 - Clean up and document/comment the irqfd assignment code.
 
 - Disallow binding multiple irqfds to an eventfd with a priority waiter,
   i.e.  ensure an eventfd is bound to at most one irqfd through the entire
   host, and add a selftest to verify eventfd:irqfd bindings are globally
   unique.
 
 - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues
   related to private <=> shared memory conversions.
 
 - Drop guest_memfd's .getattr() implementation as the VFS layer will call
   generic_fillattr() if inode_operations.getattr is NULL.
 
 - Fix issues with dirty ring harvesting where KVM doesn't bound the
   processing of entries in any way, which allows userspace to keep KVM
   in a tight loop indefinitely.
 
 - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking,
   now that KVM no longer uses assigned_device_count as a heuristic for
   either irqbypass usage or MDS mitigation.
 
 Selftests:
 
 - Fix a comment typo.
 
 - Verify KVM is loaded when getting any KVM module param so that attempting
   to run a selftest without kvm.ko loaded results in a SKIP message about
   KVM not being loaded/enabled (versus some random parameter not existing).
 
 - Skip tests that hit EACCES when attempting to access a file, and rpint
   a "Root required?" help message.  In most cases, the test just needs to
   be run with elevated permissions.

     the vCPU into VMX Root Mode (post-VMXON). Trying to detect every
     possible path leading to architecturally forbidden states is hard
     and even risks breaking userspace (if it goes from valid to valid
     state but passes through invalid states), so just wait until
     KVM_RUN to detect that the vCPU state isn't allowed

   - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling
     interception of APERF/MPERF reads, so that a "properly" configured
     VM can access APERF/MPERF. This has many caveats (APERF/MPERF
     cannot be zeroed on vCPU creation or saved/restored on suspend and
     resume, or preserved over thread migration let alone VM migration)
     but can be useful whenever you're interested in letting Linux
     guests see the effective physical CPU frequency in /proc/cpuinfo

   - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been
     created, as there's no known use case for changing the default
     frequency for other VM types and it goes counter to the very reason
     why the ioctl was added to the vm file descriptor. And also, there
     would be no way to make it work for confidential VMs with a
     "secure" TSC, so kill two birds with one stone

   - Dynamically allocation the shadow MMU's hashed page list, and defer
     allocating the hashed list until it's actually needed (the TDP MMU
     doesn't use the list)

   - Extract many of KVM's helpers for accessing architectural local
     APIC state to common x86 so that they can be shared by guest-side
     code for Secure AVIC

   - Various cleanups and fixes

  x86 (Intel):

   - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest.
     Failure to honor FREEZE_IN_SMM can leak host state into guests

   - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to
     prevent L1 from running L2 with features that KVM doesn't support,
     e.g. BTF

  x86 (AMD):

   - WARN and reject loading kvm-amd.ko instead of panicking the kernel
     if the nested SVM MSRPM offsets tracker can't handle an MSR (which
     is pretty much a static condition and therefore should never
     happen, but still)

   - Fix a variety of flaws and bugs in the AVIC device posted IRQ code

   - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware
     supports) instead of rejecting vCPU creation

   - Extend enable_ipiv module param support to SVM, by simply leaving
     IsRunning clear in the vCPU's physical ID table entry

   - Disable IPI virtualization, via enable_ipiv, if the CPU is affected
     by erratum #1235, to allow (safely) enabling AVIC on such CPUs

   - Request GA Log interrupts if and only if the target vCPU is
     blocking, i.e. only if KVM needs a notification in order to wake
     the vCPU

   - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to
     the vCPU's CPUID model

   - Accept any SNP policy that is accepted by the firmware with respect
     to SMT and single-socket restrictions. An incompatible policy
     doesn't put the kernel at risk in any way, so there's no reason for
     KVM to care

   - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM and
     use WBNOINVD instead of WBINVD when possible for SEV cache
     maintenance

   - When reclaiming memory from an SEV guest, only do cache flushes on
     CPUs that have ever run a vCPU for the guest, i.e. don't flush the
     caches for CPUs that can't possibly have cache lines with dirty,
     encrypted data

  Generic:

   - Rework irqbypass to track/match producers and consumers via an
     xarray instead of a linked list. Using a linked list leads to
     O(n^2) insertion times, which is hugely problematic for use cases
     that create large numbers of VMs. Such use cases typically don't
     actually use irqbypass, but eliminating the pointless registration
     is a future problem to solve as it likely requires new uAPI

   - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a
     "void *", to avoid making a simple concept unnecessarily difficult
     to understand

   - Decouple device posted IRQs from VFIO device assignment, as binding
     a VM to a VFIO group is not a requirement for enabling device
     posted IRQs

   - Clean up and document/comment the irqfd assignment code

   - Disallow binding multiple irqfds to an eventfd with a priority
     waiter, i.e. ensure an eventfd is bound to at most one irqfd
     through the entire host, and add a selftest to verify eventfd:irqfd
     bindings are globally unique

   - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues
     related to private <=> shared memory conversions

   - Drop guest_memfd's .getattr() implementation as the VFS layer will
     call generic_fillattr() if inode_operations.getattr is NULL

   - Fix issues with dirty ring harvesting where KVM doesn't bound the
     processing of entries in any way, which allows userspace to keep
     KVM in a tight loop indefinitely

   - Kill off kvm_arch_{start,end}_assignment() and x86's associated
     tracking, now that KVM no longer uses assigned_device_count as a
     heuristic for either irqbypass usage or MDS mitigation

  Selftests:

   - Fix a comment typo

   - Verify KVM is loaded when getting any KVM module param so that
     attempting to run a selftest without kvm.ko loaded results in a
     SKIP message about KVM not being loaded/enabled (versus some random
     parameter not existing)

   - Skip tests that hit EACCES when attempting to access a file, and
     print a "Root required?" help message. In most cases, the test just
     needs to be run with elevated permissions"

d028219a9f i3c: master: Add basic driver for the Renesas I3C controller 
Add a basic driver for the I3C controller found in Renesas RZ/G3S and
G3E SoCs. Support I3C pure busses (tested with two targets) and mixed
busses (two I3C devices plus various I2C targets). DAA and communication
with temperature sensors worked reliably at various speeds.

Missing features such as IBI, HotJoin, and target mode will be added
incrementally.

8be4d31cb8 Networking changes for 6.17. 
Core & protocols
 ----------------
 
  - Wrap datapath globals into net_aligned_data, to avoid false sharing.
 
  - Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
 
  - Add SO_INQ and SCM_INQ support to AF_UNIX.
 
  - Add SIOCINQ support to AF_VSOCK.
 
  - Add TCP_MAXSEG sockopt to MPTCP.
 
  - Add IPv6 force_forwarding sysctl to enable forwarding per interface.
 
  - Make TCP validation of whether packet fully fits in the receive
    window and the rcv_buf more strict. With increased use of HW
    aggregation a single "packet" can be multiple 100s of kB.
 
  - Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
    improves latency up to 33% for sockmap users.
 
  - Convert TCP send queue handling from tasklet to BH workque.
 
  - Improve BPF iteration over TCP sockets to see each socket exactly once.
 
  - Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
 
  - Support enabling kernel threads for NAPI processing on per-NAPI
    instance basis rather than a whole device. Fully stop the kernel NAPI
    thread when threaded NAPI gets disabled. Previously thread would stick
    around until ifdown due to tricky synchronization.
 
  - Allow multicast routing to take effect on locally-generated packets.
 
  - Add output interface argument for End.X in segment routing.
 
  - MCTP: add support for gateway routing, improve bind() handling.
 
  - Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
 
  - Add a new neighbor flag ("extern_valid"), which cedes refresh
    responsibilities to userspace. This is needed for EVPN multi-homing
    where a neighbor entry for a multi-homed host needs to be synced
    across all the VTEPs among which the host is multi-homed.
 
  - Support NUD_PERMANENT for proxy neighbor entries.
 
  - Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
 
  - Add sequence numbers to netconsole messages. Unregister netconsole's
    console when all net targets are removed. Code refactoring.
    Add a number of selftests.
 
  - Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
    should be used for an inbound SA lookup.
 
  - Support inspecting ref_tracker state via DebugFS.
 
  - Don't force bonding advertisement frames tx to ~333 ms boundaries.
    Add broadcast_neighbor option to send ARP/ND on all bonded links.
 
  - Allow providing upcall pid for the 'execute' command in openvswitch.
 
  - Remove DCCP support from Netfilter's conntrack.
 
  - Disallow multiple packet duplications in the queuing layer.
 
  - Prevent use of deprecated iptables code on PREEMPT_RT.

bf76f23aa1 Scheduler updates for v6.17: 
Core scheduler changes:
 
  - Better tracking of maximum lag of tasks in presence of different
    slices duration, for better handling of lag in the fair
    scheduler. (Vincent Guittot)
 
  - Clean up and standardize #if/#else/#endif markers throughout
    the entire scheduler code base (Ingo Molnar)
 
  - Make SMP unconditional: build the SMP scheduler's
    data structures and logic on UP kernel too, even though
    they are not used, to simplify the scheduler and remove
    around 200 #ifdef/[#else]/#endif blocks from the
    scheduler. (Ingo Molnar)
 
  - Reorganize cgroup bandwidth control interface handling
    for better interfacing with sched_ext (Tejun Heo)
 
 Balancing:
 
  - Bump sd->max_newidle_lb_cost when newidle balance fails (Chris Mason)
  - Remove sched_domain_topology_level::flags to simplify the code (Prateek Nayak)
  - Simplify and clean up build_sched_topology() (Li Chen)
  - Optimize build_sched_topology() on large machines (Li Chen)
 
 Real-time scheduling:
 
  - Add initial version of proxy execution: a mechanism for mutex-owning
    tasks to inherit the scheduling context of higher priority waiters.
    Currently limited to a single runqueue and conditional on CONFIG_EXPERT,
    and other limitations. (John Stultz, Peter Zijlstra, Valentin Schneider)
 
  - Deadline scheduler (Juri Lelli):
 
    - Fix dl_servers initialization order (Juri Lelli)
    - Fix DL scheduler's root domain reinitialization logic (Juri Lelli)
    - Fix accounting bugs after global limits change (Juri Lelli)
    - Fix scalability regression by implementing less agressive dl_server handling
      (Peter Zijlstra)
 
 PSI:
 
  - Improve scalability by optimizing psi_group_change() cpu_clock() usage
    (Peter Zijlstra)
 
 Rust changes:
 
  - Make Task, CondVar and PollCondVar methods inline to avoid unnecessary
    function calls (Kunwu Chan, Panagiotis Foliadis)
 
  - Add might_sleep() support for Rust code: Rust's "#[track_caller]"
    mechanism is used so that Rust's might_sleep() doesn't need to be
    defined as a macro (Fujita Tomonori)
 
  - Introduce file_from_location() (Boqun Feng)
 
 Debugging & instrumentation:
 
  - Make clangd usable with scheduler source code files again (Peter Zijlstra)
 
  - tools: Add root_domains_dump.py which dumps root domains info (Juri Lelli)
 
  - tools: Add dl_bw_dump.py for printing bandwidth accounting info (Juri Lelli)
 
 Misc cleanups & fixes:
 
  - Remove play_idle() (Feng Lee)
 
  - Fix check_preemption_disabled() (Sebastian Andrzej Siewior)
 
  - Do not call __put_task_struct() on RT if pi_blocked_on is set
    (Luis Claudio R. Goncalves)
 
  - Correct the comment in place_entity() (wang wei)
