- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"

- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to

human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.

fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.

our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.

"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"

"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"

order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".

total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.

also. S390 is affected.

The only difference made by CONFIG_THERMAL_WRITABLE_TRIPS is whether or
not the writable trips mask passed during thermal zone registration
will take any effect, but whoever passes a non-zero writable trips mask
to thermal_zone_device_register_with_trips() can be forgiven thinking
that it will always work.
Moreover, some thermal drivers expect user space to set trip temperature
values, so they select CONFIG_THERMAL_WRITABLE_TRIPS, possibly overriding
a manual choice to unset it and going against the design purportedly
allowing system integrators to decide on the writability of trip points
for the given kernel build. It is also set in one platform's defconfig.
Forthermore, CONFIG_THERMAL_WRITABLE_TRIPS only affects trip temperature,
because trip hysteresis is writable as long as the thermal zone provides
a callback to update it, regardless of the CONFIG_THERMAL_WRITABLE_TRIPS
value.
The above means that the symbol in question is used inconsistently and
its purpose is at least moot, so remove it and always take the writable
trip mask passed to thermal_zone_device_register_with_trips() into
account.

Since commit bfac19e239 ("fbdev: mx3fb: Remove the driver") backlight
is no longer functional.
The fbdev mx3fb driver used to automatically select
CONFIG_BACKLIGHT_CLASS_DEVICE.
Now that the mx3fb driver has been removed, enable the
CONFIG_BACKLIGHT_CLASS_DEVICE option so that backlight can still work
by default.

Patch series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages
debugfs attribute", v2.
This series refactors CONFIG_DEBUG_WX for the 5 architectures implementing
CONFIG_GENERIC_PTDUMP
First rename stuff in ARM which uses similar names while not implementing
CONFIG_GENERIC_PTDUMP.
Then define a generic version of debug_checkwx() that calls
ptdump_check_wx() when CONFIG_DEBUG_WX is set. Call it immediately after
calling mark_rodata_ro() instead of calling it at the end of every
mark_rodata_ro().
Then implement a debugfs attribute that can be used to trigger a W^X test
at anytime and regardless of CONFIG_DEBUG_WX
This patch (of 5):
CONFIG_DEBUG_WX is a core option defined in mm/Kconfig.debug
To avoid any future conflict, rename ARM version into CONFIG_ARM_DEBUG_WX.

Commit 72fee6b0a3 ("fbdev: Restrict FB_SH_MOBILE_LCDC to SuperH")
disabled availablity of the SH_MOBILE_LCDC driver on the RENESAS arch.
This innocent change has a significant side-effect on the ARM's
multi_v7_defconfig, because FB_BACKLIGHT symbol is no longer selected,
what in turn leaves BACKLIGHT_CLASS_DEVICE symbol selected only as
a module. The latter disables some backlight related code in the DRM
core, because the DRM core is set to be compiled-in in this defconfig.
This leaves all DRM display panels without integrated backlight control,
even if the needed modules have been properly loaded and probed.
Fix this by selecting BACKLIGHT_CLASS_DEVICE to be compiled-in in
multi_v7_defconfig.

The Keystone platforms used their own keystone_defconfig mostly to
enable CONFIG_ARM_LPAE which could not be added to the multi_v7 config.
Now that we have multi_v7_lpae_defconfig/lpae.config target we can and
should use that defconfig for Keystone. Add the remaining must-have
options for Keystone support to multi_v7_defconfig.

Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This extends the netfs helper library that network filesystems can use
to replace their own implementations. Both afs and 9p are ported. cifs
is ready as well but the patches are way bigger and will be routed
separately once this is merged. That will remove lots of code as well.
The overal goal is to get high-level I/O and knowledge of the page
cache and ouf of the filesystem drivers. This includes knowledge about
the existence of pages and folios
The pull request converts afs and 9p. This removes about 800 lines of
code from afs and 300 from 9p. For 9p it is now possible to do writes
in larger than a page chunks. Additionally, multipage folio support
can be turned on for 9p. Separate patches exist for cifs removing
another 2000+ lines. I've included detailed information in the
individual pulls I took.
Summary:
- Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
calls to prevent these from happening at the same time.
- Support for direct and unbuffered I/O.
- Support for write-through caching in the page cache.
- O_*SYNC and RWF_*SYNC writes use write-through rather than writing
to the page cache and then flushing afterwards.
- Support for write-streaming.
- Support for write grouping.
- Skip reads for which the server could only return zeros or EOF.
- The fscache module is now part of the netfs library and the
corresponding maintainer entry is updated.
- Some helpers from the fscache subsystem are renamed to mark them as
belonging to the netfs library.
- Follow-up fixes for the netfs library.
- Follow-up fixes for the 9p conversion"

The ir-rx51 is a pwm-based TX driver specific to the N900. This can be
handled entirely by the generic pwm-ir-tx driver, and in fact the
pwm-ir-tx driver has been compatible with ir-rx51 from the start.
Note that the suspend code in the ir-rx51 driver is unnecessary, since
during transmit, the process is not in interruptable sleep. The process
is not put to sleep until the transmit completes.

Thierry says this is not used anymore, and doesn't think it makes sense as
an iommu driver. The HW it supports is about 10 years old now and newer HW
uses different IOMMU drivers.
As this is the only driver with a GART approach, and it doesn't really
meet the driver expectations from the IOMMU core, let's just remove it
so we don't have to think about how to make it fit in.
It has a number of identified problems:
- The assignment of iommu_groups doesn't match the HW behavior
- It claims to have an UNMANAGED domain but it is really an IDENTITY
domain with a translation aperture. This is inconsistent with the core
expectation for security sensitive operations
- It doesn't implement a SW page table under struct iommu_domain so
* It can't accept a map until the domain is attached
* It forgets about all maps after the domain is detached
* It doesn't clear the HW of maps once the domain is detached
(made worse by having the wrong groups)

Inspired by Salvatore Mesoraca's earlier[1] efforts to provide some
in-tree guidance for kernel hardening Kconfig options, add a new fragment
named "hardening-basic.config" (along with some arch-specific fragments)
that enable a basic set of kernel hardening options that have the least
(or no) performance impact and remove a reasonable set of legacy APIs.
Using this fragment is as simple as running "make hardening.config".
More extreme fragments can be added[2] in the future to cover all the
recognized hardening options, and more per-architecture files can be
added too.
For now, document the fragments directly via comments. Perhaps .rst
documentation can be generated from them in the future (rather than the
other way around).

Currently the Kconfig fragments in kernel/configs and arch/*/configs
that aren't used internally aren't discoverable through "make help",
which consists of hard-coded lists of config fragments. Instead, list
all the fragment targets that have a "# Help: " comment prefix so the
targets can be generated dynamically.
Add logic to the Makefile to search for and display the fragment and
comment. Add comments to fragments that are intended to be direct targets.

Commit a2225d931f ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.
Get rid of it mechanically:
git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'
Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

Merge tag 'slab-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- SLAB deprecation:
Following the discussion at LSF/MM 2023 [1] and no objections, the
SLAB allocator is deprecated by renaming the config option (to make
its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
also updated.
- SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):
There are (very limited) cases where kmem_cache merging is
undesirable, and existing ways to prevent it are hacky. Introduce a
new flag to do that cleanly and convert the existing hacky users.
Btrfs plans to use this for debug kernel builds (that use case is
always fine), networking for performance reasons (that should be very
rare).
- Replace the usage of weak PRNGs (David Keisar Schmidt):
In addition to using stronger RNGs for the security related features,
the code is a bit cleaner.
- Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
zhaoxinchao)

As discussed at LSF/MM [1] [2] and with no objections raised there,
deprecate the SLAB allocator. Rename the user-visible option so that
users with CONFIG_SLAB=y get a new prompt with explanation during make
oldconfig, while make olddefconfig will just switch to SLUB.
In all defconfigs with CONFIG_SLAB=y remove the line so those also
switch to SLUB. Regressions due to the switch should be reported to
linux-mm and slab maintainers.

Testing on a imx6dl board with a QCA9377 SDIO Wifi chip shows that the
QCA9377 firmware takes more than three minutes to start getting loaded,
which is a very inconvenient behavior.
CONFIG_FW_LOADER_USER_HELPER and CONFIG_FW_LOADER_USER_HELPER_FALLBACK
were selected by commit 30fdd51be1 ("ARM: imx_v6_v7_defconfig:
add CONFIG_FW_LOADER_USER_HELPER")
By removing the CONFIG_FW_LOADER_USER_HELPER and
CONFIG_FW_LOADER_USER_HELPER_FALLBACK options the QCA9377 firmware is
loaded around 10 seconds after boot, which is the expected behavior.
The motivation for commit 30fdd51be1 ("ARM: imx_v6_v7_defconfig:
add CONFIG_FW_LOADER_USER_HELPER") was related to loading the SDMA
firmware,and at the time of that commit, the SDMA driver was loaded
as built-in.
Now that the SDMA driver is selected as a kernel module, its firmware can
be successfully loaded as well without the need of
CONFIG_FW_LOADER_USER_HELPER and CONFIG_FW_LOADER_USER_HELPER_FALLBACK.
Remove the selection of these two options.
Also, successfully tested the loading of the VPU firmware without
these options.

Since commit 75c2f26da0 ("PCI: imx6: Add i.MX PCIe EP mode support")
the i.MX6 PCI driver is no longer selected by default. The
existing PCI_IMX6 was made a hidden option, selected by new options
PCI_IMX6_HOST (for the existing support) and PCI_IMX6_EP (for the
endpoint mode), but there has been no corresponding update to
imx_v6_v7_defconfig so the PCI_IMX6 ends up getting disabled.
Switch imx_v6_v7_defconfig to PCI_IMX6_HOST to preserve the existing
functionality.
This is based on the same fix done in commit 0cd5780eb6 ("arm64:
defconfig: Fix unintentional disablement of PCI on i.MX").

As usual, this branch contains all the patches to enable options
for newly added device drivers in the 32-bit and 64-bit defconfig
files.
I have sorted the files according to the changes to Kconfig files,
to make it easier to check what has changed compared to the 'make
savedefconfig' output.
The most notable change this time is a series from Mark Brown
to add a 'virtconfig' target for arm64, which is for the moment
the same as the 'defconfig' target but disables all the top-level
SoC specific options in order to have a smaller and faster
kernel build.

ARM systems are often memory constrained and more often than not
use slow single-channel storage such as flash memory or MMC/SD-cards.
For any interactive systems (such as mobile phones, tablets,
chromebooks...) the BFQ I/O scheduler will be desireable.
Make sure the BFQ I/O scheduler is available on these systems.
Loongarch, MIPS, m68k, UM and S390 has also enabled BFQ in their
defconfigs, cf commit b495dfed70
"um: Cleanup CONFIG_IOSCHED_CFQ" where the motivation is that
it replaces the former CFQ scheduler.

The only missing configuration option preventing us from using
multi_v7_defconfig with the Raspberry Pi 4 is ARM_LPAE. It's needed as
the PCIe controller found on the SoC depends on 64bit addressing, yet
can't be included as not all v7 boards support LPAE.
Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will
avoid us having to duplicate and maintain multiple similar configurations.
Needless to say the Raspberry Pi 4 is not the only platform that can
benefit from this new configuration.

As explained in [1], we would like to remove SLOB if possible.
- There are no known users that need its somewhat lower memory footprint
so much that they cannot handle SLUB (after some modifications by the
previous patches) instead.
- It is an extra maintenance burden, and a number of features are
incompatible with it.
- It blocks the API improvement of allowing kfree() on objects allocated
via kmem_cache_alloc().
As the first step, rename the CONFIG_SLOB option in the slab allocator
configuration choice to CONFIG_SLOB_DEPRECATED. Add CONFIG_SLOB
depending on CONFIG_SLOB_DEPRECATED as an internal option to avoid code
churn. This will cause existing .config files and defconfigs with
CONFIG_SLOB=y to silently switch to the default (and recommended
replacement) SLUB, while still allowing SLOB to be configured by anyone
that notices and needs it. But those should contact the slab maintainers
and linux-mm@kvack.org as explained in the updated help. With no valid
objections, the plan is to update the existing defconfigs to SLUB and
remove SLOB in a few cycles.
To make SLUB more suitable replacement for SLOB, a CONFIG_SLUB_TINY
option was introduced to limit SLUB's memory overhead.
There is a number of defconfigs specifying CONFIG_SLOB=y. As part of
this patch, update them to select CONFIG_SLUB and CONFIG_SLUB_TINY.

The main changes this time are for the organization of the Kconfig
files, introducing per-vendor top-level options on arm64 to match
those on arm32, and making the platform selection on arm32 more
uniform, in particular for the remaining StrongARM platforms that
still have a couple of special cases compared to the more recent
ones.
I also did a cleanup of the old Footbridge platform, which was
the last holdout for the phys_to_dma()/dma_to_phys() interface
that is now completely gone from arm32, completing work started
by Christoph Hellwig.

Add support to detect USB flash drives and create the /dev/sd* devices.
Also add support for vfat to support USB drives formatted as FAT32.
This support will be used to enable firmware updates via USB flash
drives where the firmware image is stored in the USB drive and it's
plugged into the BMC USB port.

In commit 19e8b701e2 ("a.out: Stop building a.out/osf1 support on
alpha and m68k") the last users of a.out were disabled.
As nothing has turned up to cause this change to be reverted, let's
remove the code implementing a.out support as well.
There may be userspace users of the uapi bits left so the uapi
headers have been left untouched.
