i.MX fixes for 5.17:
- Fix sound card model for MBa8Mx board.
- Drop i.MX8MQ LCDIF port node unit-address to fix DTC warning.
- Add missing SD card detect line for imx6qdl-udoo board.
- Remove MX23_PAD_SSP1_DETECT from imx23-evk hog group. It fixes the
broken SD ard support on the board.
- A couple of fixes from Martin Kepplinger to fix the MIPI_CSI port
number on i.MX8MQ.
- Re-enable ftm_alarm0 device on ls1028a-kontron-sl28 board which was
disabled accidentally.
- Fix 'assigned-clocks-parents' typo in i.MX7ULP watchdog device node.
- Disable GPU device on imx8mn-venice-gw7902 board, as it uses
MIMX8MN5CVTI SoC which does not integrate a GPU.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps
A series of fixes for omap variants for minor issues, and a fix for a timer
regression for some omap3 beagleboard versions.
The timer fix needs to patch both the dts and the timer code because
otherwise the timer quirk handling for old dtbs will prevent the dts fix
from working.
The other changes are for issues found by automated analysis, a macasp
typo fix, and two cosmetic fixes for clocks.

The SocFPGA machine since commit b3ca9888f35f ("reset: socfpga: add an
early reset driver for SoCFPGA") uses reset controller, so it should
select RESET_CONTROLLER explicitly. Selecting ARCH_HAS_RESET_CONTROLLER
is not enough because it affects only default choice still allowing a
non-buildable configuration:

blake2s_compress_generic is weakly aliased by blake2s_compress. The
current harness for function selection uses a function pointer, which is
ordinarily inlined and resolved at compile time. But when Clang's CFI is
enabled, CFI still triggers when making an indirect call via a weak
symbol. This seems like a bug in Clang's CFI, as though it's bucketing
weak symbols and strong symbols differently. It also only seems to
trigger when "full LTO" mode is used, rather than "thin LTO".

Nonetheless, the function pointer method isn't so terrific anyway, so
this patch replaces it with a simple boolean, which also gets inlined
away. This successfully works around the Clang bug.
In general, I'm not too keen on all of the indirection involved here; it
clearly does more harm than good. Hopefully the whole thing can get
cleaned up down the road when lib/crypto is overhauled more
comprehensively. But for now, we go with a simple bandaid.

Currently, SD card fails to mount due to the following pinctrl error:
[ 11.170000] imx23-pinctrl 80018000.pinctrl: pin SSP1_DETECT already requested by 80018000.pinctrl; cannot claim for 80010000.spi

[ 11.200000] mxs-mmc 80010000.spi: Error applying setting, reverse things back
Fix it by removing the MX23_PAD_SSP1_DETECT pin from the hog group as it
is already been used by the mmc0-pins-fixup pinctrl group.
With this change the rootfs can be mounted and the imx23-evk board can
boot successfully.

First S390 complained that the sorting of the mcount sections at build
time caused the kernel to crash on their architecture. Now PowerPC is
complaining about it too. And also ARM64 appears to be having issues.
It may be necessary to also update the relocation table for the values
in the mcount table. Not only do we have to sort the table, but also
update the relocations that may be applied to the items in the table.
If the system is not relocatable, then it is fine to sort, but if it is,
some architectures may have issues (although x86 does not as it shifts all
addresses the same).
Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is
safe to do the sorting at build time.
Also update the config to compile in build time sorting in the sorttable
code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.

Patch series "remove Xen tmem leftovers".
Since the removal of the Xen tmem driver in 2019, the cleancache hooks
are entirely unused, as are large parts of frontswap. This series
against linux-next (with the folio changes included) removes
cleancaches, and cuts down frontswap to the bits actually used by zswap.
This patch (of 13):
The cleancache subsystem is unused since the removal of Xen tmem driver
in commit 814bbf49dcd0 ("xen: remove tmem driver").

When building for Thumb2, the .alt.smp.init sections that are emitted by
the ALT_UP() patching code may not be 32-bit aligned, even though the
fixup_smp_on_up() routine expects that. This results in alignment faults
at module load time, which need to be fixed up by the fault handler.
So let's align those sections explicitly, and prevent this from occurring.

The helpers that are used to implement copy_from_kernel_nofault() and
copy_to_kernel_nofault() cast a void* to a pointer to a wider type,
which may result in alignment faults on ARM if the compiler decides to
use double-word or multiple-word load/store instructions.
Only configurations that define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y
are affected, given that commit 2423de2e6f4d ("ARM: 9115/1: mm/maccess:
fix unaligned copy_{from,to}_kernel_nofault") ensures that dst and src
are sufficiently aligned otherwise.
So use the unaligned accessors for accessing dst and src in cases where
they may be misaligned.

arm32 uses software to simulate the instruction replaced
by kprobe. some instructions may be simulated by constructing
assembly functions. therefore, before executing instruction
simulation, it is necessary to construct assembly function
execution environment in C language through binding registers.
after kasan is enabled, the register binding relationship will
be destroyed, resulting in instruction simulation errors and
causing kernel panic.
the kprobe emulate instruction function is distributed in three
files: actions-common.c actions-arm.c actions-thumb.c, so disable
KASAN when compiling these files.
for example, use kprobe insert on cap_capable+20 after kasan
enabled, the cap_capable assembly code is as follows:
<cap_capable>:
e92d47f0 push {r4, r5, r6, r7, r8, r9, sl, lr}
e1a05000 mov r5, r0

e595706c ldr r7, [r5, #108] ; 0x6c
e2859014 add r9, r5, #20
......
The emulate_ldr assembly code after enabling kasan is as follows:
c06f1384 <emulate_ldr>:
e92d47f0 push {r4, r5, r6, r7, r8, r9, sl, lr}
e282803c add r8, r2, #60 ; 0x3c

Pull signal/exit/ptrace updates from Eric Biederman:
"This set of changes deletes some dead code, makes a lot of cleanups
which hopefully make the code easier to follow, and fixes bugs found
along the way.
The end-game which I have not yet reached yet is for fatal signals
that generate coredumps to be short-circuit deliverable from
complete_signal, for force_siginfo_to_task not to require changing
userspace configured signal delivery state, and for the ptrace stops
to always happen in locations where we can guarantee on all
architectures that the all of the registers are saved and available on
the stack.
Removal of profile_task_ext, profile_munmap, and profile_handoff_task
are the big successes for dead code removal this round.
A bunch of small bug fixes are included, as most of the issues
reported were small enough that they would not affect bisection so I
simply added the fixes and did not fold the fixes into the changes
they were fixing.
There was a bug that broke coredumps piped to systemd-coredump. I
dropped the change that caused that bug and replaced it entirely with
something much more restrained. Unfortunately that required some
rebasing.
Some successes after this set of changes: There are few enough calls
to do_exit to audit in a reasonable amount of time. The lifetime of
struct kthread now matches the lifetime of struct task, and the
pointer to struct kthread is no longer stored in set_child_tid. The
flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
removed. Issues where task->exit_code was examined with
signal->group_exit_code should been examined were fixed.
There are several loosely related changes included because I am
cleaning up and if I don't include them they will probably get lost.
The original postings of these changes can be found at:
https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org
https://lkml.kernel.org/r/87bl1kunjj.fsf@email.froward.int.ebiederm.org
https://lkml.kernel.org/r/87r19opkx1.fsf_-_@email.froward.int.ebiederm.org
I trimmed back the last set of changes to only the obviously correct
once. Simply because there was less time for review than I had hoped"

find_bit API and bitmap API are closely related, but inclusion paths
are different - include/asm-generic and include/linux, correspondingly.
In the past it made a lot of troubles due to circular dependencies
and/or undefined symbols. Fix this by moving find.h under include/linux.

Since commit 4064b9827063 ("mm: allow VM_FAULT_RETRY for multiple
times") allowed VM_FAULT_RETRY for multiple times, the
FAULT_FLAG_ALLOW_RETRY bit of fault_flag will not be changed in the page
fault path, so the following check is no longer needed:
flags & FAULT_FLAG_ALLOW_RETRY
So just remove it.

GZIP-compressed files end with 4 byte data that represents the size
of the original input. The decompressors (the self-extracting kernel)
exploit it to know the vmlinux size beforehand. To mimic the GZIP's
trailer, Kbuild provides cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}.
Unfortunately these macros are used everywhere despite the appended
size data is only useful for the decompressors.
There is no guarantee that such hand-crafted trailers are safely ignored.
In fact, the kernel refuses compressed initramdfs with the garbage data.
That is why usr/Makefile overrides size_append to make it no-op.
To limit the use of such broken compressed files, this commit renames
the existing macros as follows:
cmd_bzip2 --> cmd_bzip2_with_size
cmd_lzma --> cmd_lzma_with_size
cmd_lzo --> cmd_lzo_with_size
cmd_lz4 --> cmd_lz4_with_size
cmd_xzkern --> cmd_xzkern_with_size
cmd_zstd22 --> cmd_zstd22_with_size
To keep the decompressors working, I updated the following Makefiles
accordingly:
arch/arm/boot/compressed/Makefile
arch/h8300/boot/compressed/Makefile
arch/mips/boot/compressed/Makefile
arch/parisc/boot/compressed/Makefile
arch/s390/boot/compressed/Makefile
arch/sh/boot/compressed/Makefile
arch/x86/boot/compressed/Makefile
I reused the current macro names for the normal usecases; they produce
the compressed data in the proper format.
I did not touch the following:
arch/arc/boot/Makefile
arch/arm64/boot/Makefile
arch/csky/boot/Makefile
arch/mips/boot/Makefile
arch/riscv/boot/Makefile
arch/sh/boot/Makefile
kernel/Makefile
This means those Makefiles will stop appending the size data.
I dropped the 'override size_append' hack from usr/Makefile.

Pull power management updates from Rafael Wysocki:
"The most signigicant change here is the addition of a new cpufreq
'P-state' driver for AMD processors as a better replacement for the
venerable acpi-cpufreq driver.
There are also other cpufreq updates (in the core, intel_pstate, ARM
drivers), PM core updates (mostly related to adding new macros for
declaring PM operations which should make the lives of driver
developers somewhat easier), and a bunch of assorted fixes and
cleanups.
Summary:
- Add new P-state driver for AMD processors (Huang Rui).

avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
update some drivers to use these macros (Paul Cercueil).
- Allow ACPI hardware signature to be honoured during restore from
hibernation (David Woodhouse).
- Update outdated operating performance points (OPP) documentation
(Tang Yizhou).

Pull random number generator updates from Jason Donenfeld:
"These a bit more numerous than usual for the RNG, due to folks
resubmitting patches that had been pending prior and generally renewed
interest.
There are a few categories of patches in here:
1) Dominik Brodowski and I traded a series back and forth for a some
weeks that fixed numerous issues related to seeds being provided
at extremely early boot by the firmware, before other parts of the
kernel or of the RNG have been initialized, both fixing some
crashes and addressing correctness around early boot randomness.
One of these is marked for stable.
2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
extractor, and made the construction a bit safer and more
standard. This was sort of a long overdue low hanging fruit, as we
were supposed to have phased out SHA-1 usage quite some time ago
(even if all we needed here was non-invertibility). Along the way
it also made extraction 131% faster. This required a bit of
Kconfig and symbol plumbing to make things work well with the
crypto libraries, which is one of the reasons why I'm sending you
this pull early in the cycle.
3) I got rid of a truly superfluous call to RDRAND in the hot path,
which resulted in a whopping 370% increase in performance.
4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
the full series of which wasn't ready yet, but the first two
preparatory cleanups were good on their own. One of them touches
files in kernel/irq/, which is the other reason why I'm sending
you this pull early in the cycle.
5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
Mark Brown, Dominik Brodowski, and myself"

Pull ARM SoC devicetree updates from Arnd Bergmann:
"As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms. All the
newly supported SoCs belong into existing families this time:
- Qualcomm gets support for two newly announced platforms, both of
which can now work in production environments: the SDX65 5G modem
that can run a minimal Linux on its Cortex-A7 core, and the
Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3 family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two new
SoCs, plus a number of Chromebook variants and phones based on the
Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit chips
out of the box, including a number of ASUS Transformer tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining

The dt-bindings for the UART controller only allow the following values
for Meson8 SoCs:
- "amlogic,meson8b-uart", "amlogic,meson-ao-uart"
- "amlogic,meson8b-uart"
Use the correct fallback compatible string "amlogic,meson-ao-uart" for
AO UART. Drop the "amlogic,meson-uart" compatible string from the EE
domain UART controllers.
Also update the order of the clocks to match the order defined in the
yaml bindings.
