There are two big uses of do_exit. The first is it's design use to be
the guts of the exit(2) system call. The second use is to terminate
a task after something catastrophic has happened like a NULL pointer
in kernel code.
Add a function make_task_dead that is initialy exactly the same as
do_exit to cover the cases where do_exit is called to handle
catastrophic failure. In time this can probably be reduced to just a
light wrapper around do_task_dead. For now keep it exactly the same so
that there will be no behavioral differences introducing this new
concept.
Replace all of the uses of do_exit that use it for catastraphic
task cleanup with make_task_dead to make it clear what the code
is doing.
As part of this rename rewind_stack_do_exit
rewind_stack_and_make_dead.

Commit 8633ef82f1 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") made the Generic System Framebuffers (sysfb) driver able
to be built on non-x86 architectures.
But it left the efifb_setup_from_dmi() function prototype declaration in
the architecture specific headers. This could lead to the following
compiler warning as reported by the kernel test robot:
drivers/firmware/efi/sysfb_efi.c:70:6: warning: no previous prototype for function 'efifb_setup_from_dmi' [-Wmissing-prototypes]
void efifb_setup_from_dmi(struct screen_info *si, const char *opt)

The printk header file includes ratelimit_types.h for its __ratelimit()
based usage. It is required for the static initializer used in
printk_ratelimited(). It uses a raw_spinlock_t and includes the
spinlock_types.h.
PREEMPT_RT substitutes spinlock_t with a rtmutex based implementation and so
its spinlock_t implmentation (provided by spinlock_rt.h) includes rtmutex.h and
atomic.h which leads to recursive includes where defines are missing.
By including only the raw_spinlock_t defines it avoids the atomic.h
related includes at this stage.

Some thread flags can be set remotely, and so even when IRQs are disabled,
the flags can change under our feet. Generally this is unlikely to cause a
problem in practice, but it is somewhat unsound, and KCSAN will
legitimately warn that there is a data race.
To avoid such issues, a snapshot of the flags has to be taken prior to
using them. Some places already use READ_ONCE() for that, others do not.
Convert them all to the new flag accessor helpers.

pci_remap_iospace() is standard PCI core function. Architecture code can
reimplement default core implementation if needs custom arch specific
functionality.
ARM needs custom implementation due to pci_ioremap_set_mem_type() hook
which allows ARM platforms to change mem type for iospace.
Implement this pci_remap_iospace() function for ARM architecture to
correctly handle pci_ioremap_set_mem_type() hook, which allows usage of
this standard PCI core function also for platforms which needs different
mem type (e.g. Marvell Armada 375, 38x and 39x).

Pull folio fixes from Matthew Wilcox:
"In the course of preparing the folio changes for iomap for next merge
window, we discovered some problems that would be nice to address now:
- Renaming multi-page folios to large folios.
mapping_multi_page_folio_support() is just a little too long, so we
settled on mapping_large_folio_support(). That meant renaming, eg
folio_test_multi() to folio_test_large().
Rename AS_THP_SUPPORT to match
- I hadn't included folio wrappers for zero_user_segments(), etc.
Also, multi-page^W^W large folio support is now independent of
CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need
to fall back to the out-of-line zero_user_segments().
Remove FS_THP_SUPPORT to match

suggested that we just add linux/cacheflush.h and not rely on

The thermal pressure is a mechanism which is used for providing
information about reduced CPU performance to the scheduler. Usually code
has to convert the value from frequency units into capacity units,
which are understandable by the scheduler. Create a common conversion code
which can be just used via a handy API.
Internally, the topology_update_thermal_pressure() operates on frequency
in MHz and max CPU frequency is taken from 'freq_factor' (per-cpu).

In the new behavior, the sja1105 driver expects there to be explicit
RGMII delays present on the fixed-link ports, otherwise it will complain
that it falls back to legacy behavior, which is to apply RGMII delays
incorrectly derived from the phy-mode string.
In this case, the legacy behavior of the driver is to not apply delays
in any direction (mostly because the SJA1105T can't do that, so this
board uses PCB traces). To preserve that but also silence the driver,
use explicit delays of 0 ns. The delay information from the phy-mode is
ignored by new kernels (it's still RGMII as long as it's "rgmii*"
something), and the explicit {rx,tx}-internal-delay-ps properties are
ignored by old kernels, so the change works both ways.

The kmap_local conversion broke the ARM architecture, because the new
code assumes that all PTEs used for creating kmaps form a linear array
in memory, and uses array indexing to look up the kmap PTE belonging to
a certain kmap index.
On ARM, this cannot work, not only because the PTE pages may be
non-adjacent in memory, but also because ARM/!LPAE interleaves hardware
entries and extended entries (carrying software-only bits) in a way that
is not compatible with array indexing.
Fortunately, this only seems to affect configurations with more than 8
CPUs, due to the way the per-CPU kmap slots are organized in memory.
Work around this by permitting an architecture to set a Kconfig symbol
that signifies that the kmap PTEs do not form a lineary array in memory,
and so the only way to locate the appropriate one is to walk the page
tables.

Protect perf_guest_cbs with RCU to fix multiple possible errors. Luckily,
all paths that read perf_guest_cbs already require RCU protection, e.g. to
protect the callback chains, so only the direct perf_guest_cbs touchpoints
need to be modified.
Bug #1 is a simple lack of WRITE_ONCE/READ_ONCE behavior to ensure
perf_guest_cbs isn't reloaded between a !NULL check and a dereference.
Fixed via the READ_ONCE() in rcu_dereference().
Bug #2 is that on weakly-ordered architectures, updates to the callbacks
themselves are not guaranteed to be visible before the pointer is made
visible to readers. Fixed by the smp_store_release() in
rcu_assign_pointer() when the new pointer is non-NULL.
Bug #3 is that, because the callbacks are global, it's possible for
readers to run in parallel with an unregisters, and thus a module
implementing the callbacks can be unloaded while readers are in flight,
resulting in a use-after-free. Fixed by a synchronize_rcu() call when
unregistering callbacks.
Bug #1 escaped notice because it's extremely unlikely a compiler will
reload perf_guest_cbs in this sequence. perf_guest_cbs does get reloaded
for future derefs, e.g. for ->is_user_mode(), but the ->is_in_guest()
guard all but guarantees the consumer will win the race, e.g. to nullify
perf_guest_cbs, KVM has to completely exit the guest and teardown down
all VMs before KVM start its module unload / unregister sequence. This
also makes it all but impossible to encounter bug #3.
Bug #2 has not been a problem because all architectures that register
callbacks are strongly ordered and/or have a static set of callbacks.
But with help, unloading kvm_intel can trigger bug #1 e.g. wrapping
perf_guest_cbs with READ_ONCE in perf_misc_flags() while spamming
kvm_intel module load/unload leads to:

In the current code, the actual max tail call count is 33 which is greater
than MAX_TAIL_CALL_CNT (defined as 32). The actual limit is not consistent
with the meaning of MAX_TAIL_CALL_CNT and thus confusing at first glance.
We can see the historical evolution from commit 04fd61ab36 ("bpf: allow
bpf programs to tail-call other bpf programs") and commit f9dabe016b
("bpf: Undo off-by-one in interpreter tail call count limit"). In order
to avoid changing existing behavior, the actual limit is 33 now, this is
reasonable.
After commit 874be05f52 ("bpf, tests: Add tail call test suite"), we can
see there exists failed testcase.
On all archs when CONFIG_BPF_JIT_ALWAYS_ON is not set:
# echo 0 > /proc/sys/net/core/bpf_jit_enable
# modprobe test_bpf
# dmesg | grep -w FAIL
Tail call error path, max count reached jited:0 ret 34 != 33 FAIL
On some archs:
# echo 1 > /proc/sys/net/core/bpf_jit_enable
# modprobe test_bpf
# dmesg | grep -w FAIL
Tail call error path, max count reached jited:1 ret 34 != 33 FAIL
Although the above failed testcase has been fixed in commit 18935a72eb
("bpf/tests: Fix error in tail call limit tests"), it would still be good
to change the value of MAX_TAIL_CALL_CNT from 32 to 33 to make the code
more readable.
The 32-bit x86 JIT was using a limit of 32, just fix the wrong comments and
limit to 33 tail calls as the constant MAX_TAIL_CALL_CNT updated. For the
mips64 JIT, use "ori" instead of "addiu" as suggested by Johan Almbladh.
For the riscv JIT, use RV_REG_TCC directly to save one register move as
suggested by Björn Töpel. For the other implementations, no function changes,
it does not change the current limit 33, the new value of MAX_TAIL_CALL_CNT
can reflect the actual max tail call count, the related tail call testcases
in test_bpf module and selftests can work well for the interpreter and the
JIT.
Here are the test results on x86_64:
# uname -m
x86_64
# echo 0 > /proc/sys/net/core/bpf_jit_enable
# modprobe test_bpf test_suite=test_tail_calls

The I2C interrupt controller line is off by 32 because the datasheet
describes interrupt inputs into the GIC which are for Shared Peripheral
Interrupts and are starting at offset 32. The ARM GIC binding expects
the SPI interrupts to be numbered from 0 relative to the SPI base.

replaces the bit-banged i2c-gpio provided i2c functionality
with the hardware in the SoC.
During review of the MR32, Florian Fainelli pointed out that the
SoC has a real I2C-controller. Furthermore, the connected pins
(SDA and SCL) would line up perfectly for use. Back then I couldn't
get it working though and I left it with i2c-gpio (which worked).
Now we know the reason: the interrupt was incorrectly specified.
(Hence, this patch depends on Florian Fainelli's
"ARM: dts: BCM5301X: Fix I2C controller interrupt" patch).

The recently added SMP support needs to be disabled for this board as
the kernel panics executing /init with it, even though the CPUs seem to

ARM: 9156/1: drop cc-option fallbacks for architecture selection
ARM: 9155/1: fix early early_iounmap()
Naresh and Antonio ran into a build failure with latest Debian
armhf compilers, with lots of output like
tmp/ccY3nOAs.s:2215: Error: selected processor does not support `cpsid i' in ARM mode
As it turns out, $(cc-option) fails early here when the FPU is not
selected before CPU architecture is selected, as the compiler
option check runs before enabling -msoft-float, which causes
a problem when testing a target architecture level without an FPU:
cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU
Passing e.g. -march=armv6k+fp in place of -march=armv6k would avoid this
issue, but the fallback logic is already broken because all supported
compilers (gcc-5 and higher) are much more recent than these options,
and building with -march=armv5t as a fallback no longer works.
The best way forward that I see is to just remove all the checks, which
also has the nice side-effect of slightly improving the startup time for
'make'.
The -mtune=marvell-f option was apparently never supported by any mainline
compiler, and the custom Codesourcery gcc build that did support is
now too old to build kernels, so just use -mtune=xscale unconditionally
for those.
This should be safe to apply on all stable kernels, and will be required
in order to keep building them with gcc-11 and higher.

After switched page size from 64KB to 4KB on several arm64 servers here,
kmemleak starts to run out of early memory pool due to a huge number of
those early_pgtable_alloc() calls:
kmemleak_alloc_phys()
memblock_alloc_range_nid()
memblock_phys_alloc_range()
early_pgtable_alloc()
init_pmd()
alloc_init_pud()
__create_pgd_mapping()
__map_memblock()
paging_init()
setup_arch()
start_kernel()
Increased the default value of DEBUG_KMEMLEAK_MEM_POOL_SIZE by 4 times
won't be enough for a server with 200GB+ memory. There isn't much
interesting to check memory leaks for those early page tables and those
early memory mappings should not reference to other memory. Hence, no
kmemleak false positives, and we can safely skip tracking those early
allocations from kmemleak like we did in the commit fed84c7852
("mm/memblock.c: skip kmemleak for kasan_init()") without needing to
introduce complications to automatically scale the value depends on the
runtime memory size etc. After the patch, the default value of
DEBUG_KMEMLEAK_MEM_POOL_SIZE becomes sufficient again.

Since memblock_free() operates on a physical range, make its name
reflect it and rename it to memblock_phys_free(), so it will be a
logical counterpart to memblock_phys_alloc().
The callers are updated with the below semantic patch:

expression addr;
expression size;

- memblock_free(addr, size);

These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

The SoC updates this time are mainly removing obsolete code from the
OMAP2 platform, another step in the eternal cleanup of that platform.
There are two new SoCs getting added: STMicroelectronics stm32mp13 and
Microchip lan966. Both fit into existing platforms and require minimal
changes here.
A couple of MAINTAINER file updates relate to those changes, and
update some file paths.

The end goal of the current buffer overflow detection work[0] is to gain
full compile-time and run-time coverage of all detectable buffer overflows
seen via array indexing or memcpy(), memmove(), and memset(). The str*()
family of functions already have full coverage.
While much of the work for these changes have been on-going for many
releases (i.e. 0-element and 1-element array replacements, as well as
avoiding false positives and fixing discovered overflows[1]), this series
contains the foundational elements of several related buffer overflow
detection improvements by providing new common helpers and FORTIFY_SOURCE
changes needed to gain the introspection required for compiler visibility
into array sizes. Also included are a handful of already Acked instances
using the helpers (or related clean-ups), with many more waiting at the
ready to be taken via subsystem-specific trees[2]. The new helpers are:
- struct_group() for gaining struct member range introspection.
- memset_after() and memset_startat() for clearing to the end of structures.
- DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs.
Also included is the beginning of the refactoring of FORTIFY_SOURCE to
support memcpy() introspection, fix missing and regressed coverage under
GCC, and to prepare to fix the currently broken Clang support. Finishing
this work is part of the larger series[0], but depends on all the false
positives and buffer overflow bug fixes to have landed already and those
that depend on this series to land.
As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time
and run-time tests are added for FORTIFY_SOURCE and the mem*()-family
functions respectively. The compile time tests have found a legitimate
(though corner-case) bug[6] already.
Please note that the appearance of "panic" and "BUG" in the
FORTIFY_SOURCE refactoring are the result of relocating existing code,
and no new use of those code-paths are expected nor desired.
Finally, there are two tree-wide conversions for 0-element arrays and
flexible array unions to gain sane compiler introspection coverage that
result in no known object code differences.
After this series (and the changes that have now landed via netdev
and usb), we are very close to finally being able to build with
-Warray-bounds and -Wzero-length-bounds. However, due corner cases in
GCC[3] and Clang[4], I have not included the last two patches that turn
on these options, as I don't want to introduce any known warnings to
the build. Hopefully these can be solved soon.

Pull scheduler updates from Thomas Gleixner:
- Revert the printk format based wchan() symbol resolution as it can
leak the raw value in case that the symbol is not resolvable.
- Make wchan() more robust and work with all kind of unwinders by
enforcing that the task stays blocked while unwinding is in progress.
- Prevent sched_fork() from accessing an invalid sched_task_group
- Improve asymmetric packing logic
- Extend scheduler statistics to RT and DL scheduling classes and add
statistics for bandwith burst to the SCHED_FAIR class.
- Properly account SCHED_IDLE entities
- Prevent a potential deadlock when initial priority is assigned to a
newly created kthread. A recent change to plug a race between cpuset
and __sched_setscheduler() introduced a new lock dependency which is
now triggered. Break the lock dependency chain by moving the priority
assignment to the thread function.
- Fix the idle time reporting in /proc/uptime for NOHZ enabled systems.
- Improve idle balancing in general and especially for NOHZ enabled
systems.
- Provide proper interfaces for live patching so it does not have to
fiddle with scheduler internals.
- Add cluster aware scheduling support.
- A small set of tweaks for RT (irqwork, wait_task_inactive(), various
scheduler options and delaying mmdrop)
- The usual small tweaks and improvements all over the place

Pull memory folios from Matthew Wilcox:
"Add memory folios, a new type to represent either order-0 pages or the
head page of a compound page. This should be enough infrastructure to
support filesystems converting from pages to folios.
The point of all this churn is to allow filesystems and the page cache
to manage memory in larger chunks than PAGE_SIZE. The original plan
was to use compound pages like THP does, but I ran into problems with
some functions expecting only a head page while others expect the
precise page containing a particular byte.
The folio type allows a function to declare that it's expecting only a
head page. Almost incidentally, this allows us to remove various calls
to VM_BUG_ON(PageTail(page)) and compound_head().
This converts just parts of the core MM and the page cache. For 5.17,
we intend to convert various filesystems (XFS and AFS are ready; other
filesystems may make it) and also convert more of the MM and page
cache to folios. For 5.18, multi-page folios should be ready.
The multi-page folios offer some improvement to some workloads. The
80% win is real, but appears to be an artificial benchmark (postgres
startup, which isn't a serious workload). Real workloads (eg building
the kernel, running postgres in a steady state, etc) seem to benefit
between 0-10%. I haven't heard of any performance losses as a result
of this series. Nobody has done any serious performance tuning; I
imagine that tweaking the readahead algorithm could provide some more
interesting wins. There are also other places where we could choose to
create large folios and currently do not, such as writes that are
larger than PAGE_SIZE.
I'd like to thank all my reviewers who've offered review/ack tags:
Christoph Hellwig, David Howells, Jan Kara, Jeff Layton, Johannes
Weiner, Kirill A. Shutemov, Michal Hocko, Mike Rapoport, Vlastimil
Babka, William Kucharski, Yu Zhao and Zi Yan.

If available, we use the __builtin_thread_pointer() helper to get the
value of the TLS register, to help the compiler understand that it
doesn't need to reload it every time we access 'current'.
Unfortunately, Clang fails to emit the MRC system register read
directly when building for Thumb2, and instead, it issues a call to the
__aeabi_read_tp helper, which the kernel does not provide, and so this
result in link failures at build time.
So create a special case for this, and emit the MRC directly using an
asm() block, just like we do when the helper is not available to begin
with.

The code that implements the rarely used PID_IN_CONTEXTIDR feature
dereferences the 'task' field of struct thread_info directly, and this
is no longer possible when THREAD_INFO_IN_TASK=y, as the 'task' field is
omitted from the struct definition in that case. Instead, we should just
cast the thread_info pointer to a task_struct pointer, given that the
former is now the first member of the latter.
So use a helper that abstracts this, and provide implementations for
both cases.

The Ux500 PRCC (peripheral reset and clock controller) can also
control reset of the IP blocks, not just clocks. As the PRCC is probed
as a clock controller and we have other platforms implementing combined
clock and reset controllers, follow this pattern and implement the PRCC
rest controller as part of the clock driver.
The reset controller needs to be selected from the machine as Ux500 has

The RPM and RPMh sleep stats are introduced on a number of platforms, to
aid the enablement of entering low power mode.
The MSM8916 support receives some polishing touches, followed by
introduction of the necessary pieces to use the DeviceTree on 32-bit
variants of the MSM8916 platform, in particular to boot the secondary
CPUs. Based on this support for the Samsung Galaxy S4 Mini Value Edition
is introduced.
The Asus Zenfone 2 Laser gained touchscreen, sensors and sdcard support.
MSM8996 got support for the its crypto hardware and the Xiaomi Mi 5
gained a description of its LCD panel.
The Trogdor device on SC7180 gained support for a second source eDP
brigde, while SC7280 gains PCIe support and the newly introduced
Herobrine device.
Both MSM8916 and SDM845 has their standalong SMEM node dropped, in favour
of the newly introduced support for specifying the compatible directly
on the reserved-memory node.
The SM7225 platform is introduced, as a derrivative of SM6350, initial
support for the PM6350 PMIC and based on this the Fairphone 4 is
introduced.
The RB3 and RB5 devices gains msm-id and board-id, to allow the two DTBs
to be baked into a single boot.img that can be booted on both devices.
As the GDSC driver has been extended to properly describe the
relationship between MMCX and MDSS_GDSC, the now deprecated mmcx
regulator is removed from SM8250.
SM8350 gained CPU topology, idle-states and fastrpc support. FastRPC was
also added for SM8150 and the SA8155p ADP got a couple of remoteprocs
enabled.
Additionally a number of DT validation issues was corrected across the
various platforms and devices.

1. Convert Exynos ChipID and ASV driver to a module and make it a
default, instead of selected. The driver is not essential, so it
could be disabled, if needed.
2. Add support for Exynos850 and Exynos Auto v9 to Exynos ChipID and ASV
driver.
3. Get rid of HAVE_S3C_RTC because it was adding just another layer
instead of direct dependencies.
4. Minor cleanups.

Samsung SoC drivers changes for v5.16
1. Convert Exynos ChipID and ASV driver to a module and make it a
default, instead of selected. The driver is not essential, so it
could be disabled, if needed.
2. Add support for Exynos850 and Exynos Auto v9 to Exynos ChipID and ASV
driver.
3. Get rid of HAVE_S3C_RTC because it was adding just another layer
instead of direct dependencies.
4. Minor cleanups.

Now that entry code handles IRQ entry (including setting the IRQ regs)
before calling irqchip code, irqchip code can safely call
generic_handle_domain_irq(), and there's no functional reason for it to
call handle_domain_irq().
Let's cement this split of responsibility and remove handle_domain_irq()
entirely, updating irqchip drivers to call generic_handle_domain_irq().
For consistency, handle_domain_nmi() is similarly removed and replaced
with a generic_handle_domain_nmi() function which also does not perform
any entry logic.
Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire
when they were called in an inappropriate context. So that we can
identify similar issues going forward, similar WARN_ON_ONCE() logic is
added to the generic_handle_*() functions, and comments are updated for
clarity and consistency.

a definition makes it build correctly.

For platforms that are not yet converted to ARCH_MULTIPLATFORM,
we can disable CONFIG_ARM_PATCH_PHYS_VIRT, which in turn requires
setting a correct address here.
As we actualy know what all the values are supposed to be based
on the old mach/memory.h header file contents (from git history),
we can just add them here.
This also solves a problem in Kconfig where 'make randconfig'
fails to continue if no number is selected for a 'hex' option.
Users can still override the number at configuration time, e.g.
when the memory visible to the kernel starts at a nonstandard
address on some machine, but it should no longer be required
now.
I originally posted this back in 2016, but the problem still
persists. The patch has gotten much simpler though, as almost
all platforms rely on ARM_PATCH_PHYS_VIRT now.

A lot of randconfig builds end up not selecting any machine type at
all. This is generally fine for the purpose of compile testing, but
of course it means that the kernel is not usable on actual hardware,
and it causes a warning about this fact.
As most of the build bots now force-enable CONFIG_COMPILE_TEST for
randconfig builds, use that as a guard to control whether we warn
on this type of broken configuration.
We could do the same for the missing-cpu-type warning, but those
configurations fail to build much earlier.

We can currently build a multi-cpu enabled kernel that allows both ARMv4
and ARMv5 CPUs, and also supports THUMB mode in user space.
However, returning to user space in this configuration with the usr_ret
macro requires the use of the 'bx' instruction, which is refused by
the assembler:
arch/arm/kernel/entry-armv.S: Assembler messages:
arch/arm/kernel/entry-armv.S:937: Error: selected processor does not support `bx lr' in ARM mode
arch/arm/kernel/entry-armv.S:960: Error: selected processor does not support `bx lr' in ARM mode
arch/arm/kernel/entry-armv.S:1003: Error: selected processor does not support `bx lr' in ARM mode
<instantiation>:2:2: note: instruction requires: armv4t
bx lr
While it would be possible to handle this correctly in principle, doing so
seems to not be worth it, if we can simply avoid the problem by enforcing
that a kernel supporting both ARMv4 and a later CPU architecture cannot
run THUMB binaries.
This turned up while build-testing with clang; for some reason,
gcc never triggered the problem.

In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have arch/arm
perform all the irqentry accounting in its entry code.
For configurations with CONFIG_GENERIC_IRQ_MULTI_HANDLER, we can use
generic_handle_arch_irq(). Other than asm_do_IRQ(), all C calls to
handle_IRQ() are from irqchip handlers which will be called from
generic_handle_arch_irq(), so to avoid double accounting IRQ entry, the
entry logic is moved from handle_IRQ() into asm_do_IRQ().
For ARMv7M the entry assembly is tightly coupled with the NVIC irqchip, and
while the entry code should logically live under arch/arm/, moving the
entry logic there makes things more convoluted. So for now, place the
entry logic in the NVIC irqchip, but separated into a separate
function to make the split of responsibility clear.
For all other configurations without CONFIG_GENERIC_IRQ_MULTI_HANDLER,
IRQ entry is already handled in arch code, and requires no changes.
There should be no functional change as a result of this patch.

Going forward we want architecture/entry code to perform all the
necessary work to enter/exit IRQ context, with irqchip code merely
handling the mapping of the interrupt to any handler(s). Among other
reasons, this is necessary to consistently fix some longstanding issues
with the ordering of lockdep/RCU/tracing instrumentation which many
architectures get wrong today in their entry code.
Importantly, rcu_irq_{enter,exit}() must be called precisely once per
IRQ exception, so that rcu_is_cpu_rrupt_from_idle() can correctly
identify when an interrupt was taken from an idle context which must be
explicitly preempted. Currently handle_domain_irq() calls
rcu_irq_{enter,exit}() via irq_{enter,exit}(), but entry code needs to
be able to call rcu_irq_{enter,exit}() earlier for correct ordering
across lockdep/RCU/tracing updates for sequences such as:
lockdep_hardirqs_off(CALLER_ADDR0);
rcu_irq_enter();
trace_hardirqs_off_finish();
To permit each architecture to be converted to the new style in turn,
this patch adds a new CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY selected by all
current users of HANDLE_DOMAIN_IRQ, which gates the existing behaviour.
When CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY is not selected,
handle_domain_irq() requires entry code to perform the
irq_{enter,exit}() work, with an explicit check for this matching the
style of handle_domain_nmi().
Subsequent patches will:
1) Add the necessary IRQ entry accounting to each architecture in turn,
dropping CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY from that architecture's
Kconfig.
2) Remove CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY once it is no longer
selected.
3) Convert irqchip drivers to consistently use
generic_handle_domain_irq() rather than handle_domain_irq().
4) Remove handle_domain_irq() and CONFIG_HANDLE_DOMAIN_IRQ.
... which should leave us with a clear split of responsiblity across the
entry and irqchip code, making it possible to perform additional
cleanups and fixes for the aforementioned longstanding issues with entry
code.
There should be no functional change as a result of this patch.

Documentation/kbuild/makefiles.rst suggests to use "archclean" for
cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.
Since commit d92cc4d516 ("kbuild: require all architectures to have
arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for
all architectures. This can take advantage of the parallel option (-j)
for "make clean".

Since the kretprobe replaces the function return address with
the kretprobe_trampoline on the stack, arm unwinder shows it
instead of the correct return address.
This finds the correct return address from the per-task
kretprobe_instances list and verify it is in between the
caller fp and callee fp.
Note that this supports both GCC and clang if CONFIG_FRAME_POINTER=y
and CONFIG_ARM_UNWIND=n. For the ARM unwinder, this is still
not working correctly.

Currently kretprobe on ARM just fills r0-r11 of pt_regs, but
that is not enough for the stacktrace. Moreover, from the user
kretprobe handler, stacktrace needs a frame pointer on the
__kretprobe_trampoline.
This adds a frame pointer on __kretprobe_trampoline for both gcc
and clang case. Those have different frame pointer so we need
different but similar stack on pt_regs.
Gcc makes the frame pointer (fp) to point the 'pc' address of
the {fp, ip (=sp), lr, pc}, this means {r11, r13, r14, r15}.
Thus if we save the r11 (fp) on pt_regs->r12, we can make this
set on the end of pt_regs.
On the other hand, Clang makes the frame pointer to point the
'fp' address of {fp, lr} on stack. Since the next to the
pt_regs->lr is pt_regs->sp, I reused the pair of pt_regs->fp
and pt_regs->ip.
So this stores the 'lr' on pt_regs->ip and make the fp to point
pt_regs->fp.
For both cases, saves __kretprobe_trampoline address to
pt_regs->lr, so that the stack tracer can identify this frame
pointer has been made by the __kretprobe_trampoline.
Note that if the CONFIG_FRAME_POINTER is not set, this keeps
fp as is.

Currently the stacktrace on clang compiled arm kernel uses the 'lr'
register to find the first frame address from pt_regs. However, that
is wrong after calling another function, because the 'lr' register
is used by 'bl' instruction and never be recovered.
As same as gcc arm kernel, directly use the frame pointer (r11) of
the pt_regs to find the first frame address.
Note that this fixes kretprobe stacktrace issue only with
CONFIG_UNWINDER_FRAME_POINTER=y. For the CONFIG_UNWINDER_ARM,
we need another fix.

tested on ts7250 (EP9302).
Only setting rate and change parent tested for, as they
are missing on ts7250:
- video
- I2S
- ADC/KEYPAD
- PWM
Only video and I2S clock are interesting, as they are
GATE + double DIV + MUX, all other are pretty much
common but require ep93xx_syscon_swlocked_write to set

With the conversion of rockchip-usb-phy.yaml a long time used fallback
string for rk3066a/rk3188 was added. The linux driver doesn't do much with
the GRF phy address range, however the u-boot driver rockchip_usb2_phy.c
does. The bits in GRF_UOC0_CON2 for rk3066a/rk3188 and rk3288 for example
don't match. Remove the usb-phy fallback string for rk3066a/rk3188
to prevent possible strange side effects.
