Pull arm64 updates from Catalin Marinas:
"A quick summary: perf support for Branch Record Buffer Extensions
(BRBE), typical PMU hardware updates, small additions to MTE for
store-only tag checking and exposing non-address bits to signal
handlers, HAVE_LIVEPATCH enabled on arm64, VMAP_STACK forced on.
There is also a TLBI optimisation on hardware that does not require
break-before-make when changing the user PTEs between contiguous and
non-contiguous.
More details:
Perf and PMU updates:
- Add support for new (v3) Hisilicon SLLC and DDRC PMUs
- Add support for Arm-NI PMU integrations that share interrupts
between clock domains within a given instance
- Allow SPE to be configured with a lower sample period than the
minimum recommendation advertised by PMSIDR_EL1.Interval
- Add suppport for Arm's "Branch Record Buffer Extension" (BRBE)
- Adjust the perf watchdog period according to cpu frequency changes
- Minor driver fixes and cleanups
Hardware features:
- Support for MTE store-only checking (FEAT_MTE_STORE_ONLY)
- Support for reporting the non-address bits during a synchronous MTE
tag check fault (FEAT_MTE_TAGGED_FAR)
- Optimise the TLBI when folding/unfolding contiguous PTEs on
hardware with FEAT_BBM (break-before-make) level 2 and no TLB
conflict aborts
Software features:
- Enable HAVE_LIVEPATCH after implementing arch_stack_walk_reliable()
and using the text-poke API for late module relocations
- Force VMAP_STACK always on and change arm64_efi_rt_init() to use
arch_alloc_vmap_stack() in order to avoid KASAN false positives
ACPI:
- Improve SPCR handling and messaging on systems lacking an SPCR
table
Debug:
- Simplify the debug exception entry path
- Drop redundant DBG_MDSCR_* macros
Kselftests:
- Cleanups and improvements for SME, SVE and FPSIMD tests
Miscellaneous:
- Optimise loop to reduce redundant operations in contpte_ptep_get()
- Remove ISB when resetting POR_EL0 during signal handling
- Mark the kernel as tainted on SEA and SError panic
- Remove redundant gcs_free() call"

Pull timekeeping and VDSO updates from Thomas Gleixner:
- Introduce support for auxiliary timekeepers
PTP clocks can be disconnected from the universal CLOCK_TAI reality
for various reasons including regularatory requirements for
functional safety redundancy.
The kernel so far only supports a single notion of time, which means
that all clocks are correlated in frequency and only differ by offset
to each other.
Access to non-correlated PTP clocks has been available so far only
through the file descriptor based "POSIX clock IDs", which are
subject to locking and have to go all the way out to the hardware.
The access is not only horribly slow, as it has to go all the way out
to the NIC/PTP hardware, but that also prevents the kernel to read
the time of such clocks e.g. from the network stack, where it is
required for TSN networking both on the transmit and receive side
unless the hardware provides offloading.
The auxiliary clocks provide a mechanism to support arbitrary clocks
which are not correlated to the system clock. This is not restricted
to the PTP use case on purpose as there is no kernel side association
of these clocks to a particular PTP device because that's a pure user
space configuration decision. Having them independent allows to
utilize them for other purposes and also enables them to be tested
without hardware dependencies.
To avoid pointless overhead these clocks have to be enabled
individualy via a new sysfs interface to reduce the overhead to a
single compare in the hotpath if they are enabled at the Kconfig
level at all.
These clocks utilize the existing timekeeping/NTP infrastructures,
which has been made possible over the recent releases by incrementaly
converting these infrastructures over from a single static instance
to a multi-instance pointer based implementation without any
performance regression reported.
The auxiliary clocks provide the same "emulation" of a "correct"
clock as the existing CLOCK_* variants do with an independent
instance of data and provide the same steering mechanism through the
existing sys_clock_adjtime() interface, which has been confirmed to
work by the chronyd(8) maintainer.
That allows to provide lockless kernel internal and VDSO support so
that applications and kernel internal functionalities can access
these clocks without restrictions and at the same performance as the
existing system clocks.
- Avoid double notifications in the adjtimex() syscall. Not a big
issue, but a trivial to avoid latency source.

Pull new SoC support from Arnd Bergmann:
"These five newly supported chips come with both devicetree
descriptions and the changes to wire them up to the build system for
easier bisection.
The chips in question are:
- Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
in the product line that started with the Digital StrongARM SA1100
based PDAs and continued with the Intel PXA2xx that dominated early
smartphones. This one only made it only into a few products before
the entire product line was cut in 2015.
- The QiLai SoC is made by RISC-V core designer Andes Technologies
and is in the 'Voyager' reference board in MicroATX form factor. It
uses four in-order AX45MP cores, which is the midrange product from
Andes.
- CIX P1 is one of the few Arm chips designed for small workstations,
and this one uses 12 Cortex-A720/A520 cores, making it also one of
the only ARMv9.2 machines that one can but at the moment.
- Axiado AX3000 is an embedded chip with relative small Cortex-A53
CPU cores described as a "Trusted Control/Compute Unit" that can be
used as a BMC in servers. In addition to the usual I/O, this one
comes with 10GBit ethernet and and a 4TOPS NPU.
- Sophgo SG2000 is an embedded chip that comes with both RISC-V and
Arm cores that can run Linux. This was already supported for RISC-V
but now it also works on Arm
One more chip, the Black Sesame C1200 did not make it in tirm for the
merge window"

Pull SoC devicetree updates from Arnd Bergmann:
"There are a few new variants of existing chips:
- mt6572 is an older mobile phone chip from mediatek that was
extremely popular a decade ago but never got upstreamed until now
- exynos2200 is a recent high-end mobile phone chip used in a few
Samsung phones like the Galaxy S22
- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it
There are five more chips in a separate branch, as those are new chip
families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly added
machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and Sophgo
sg2042
- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95
- Two newly added ASPEED BMC based motherboards, and one that got
removed
- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm

Pull crypto library updates from Eric Biggers:
"This is the main crypto library pull request for 6.17. The main focus
this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
and establishing conventions for lib/crypto/ going forward:
- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
most of the SHA-512 code) into lib/crypto/. This includes both the
generic and architecture-optimized code. Greatly simplify how the
architecture-optimized code is integrated. Add an easy-to-use
library API for each SHA variant, including HMAC support. Finally,
reimplement the crypto_shash support on top of the library API.
- Apply the same reorganization to the SHA-256 code (and also SHA-224
which shares most of the SHA-256 code). This is a somewhat smaller
change, due to my earlier work on SHA-256. But this brings in all
the same additional improvements that I made for SHA-1 and SHA-512.
There are also some smaller changes:
- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
these algorithms it's just a move, not a full reorganization yet.
- Fix the MIPS chacha-core.S to build with the clang assembler.
- Fix the Poly1305 functions to work in all contexts.
- Fix a performance regression in the x86_64 Poly1305 code.
- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
Note that since the new organization of the SHA code is much simpler,
the diffstat of this pull request is negative, despite the addition of
new fully-documented library APIs for multiple SHA and HMAC-SHA
variants.
These APIs will allow further simplifications across the kernel as
users start using them instead of the old-school crypto API. (I've
already written a lot of such conversion patches, removing over 1000
more lines of code. But most of those will target 6.18 or later)"

Pull CRC updates from Eric Biggers:
- Reorganize the architecture-optimized CRC code
It now lives in lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/,
and it is no longer artificially split into separate generic and arch
modules. This allows better inlining and dead code elimination
The generic CRC code is also no longer exported, simplifying the API.
(This mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request)
- Improve crc32c() performance on newer x86_64 CPUs on long messages by
enabling the VPCLMULQDQ optimized code
- Simplify the crypto_shash wrappers for crc32_le() and crc32c()
Register just one shash algorithm for each that uses the (fully
optimized) library functions, instead of unnecessarily providing
direct access to the generic CRC code
- Remove unused and obsolete drivers for hardware CRC engines
- Remove CRC-32 combination functions that are no longer used
- Add kerneldoc for crc32_le(), crc32_be(), and crc32c()

Pull fileattr updates from Christian Brauner:
"This introduces the new file_getattr() and file_setattr() system calls
after lengthy discussions.
Both system calls serve as successors and extensible companions to
the FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR system calls which have
started to show their age in addition to being named in a way that
makes it easy to conflate them with extended attribute related
operations.
These syscalls allow userspace to set filesystem inode attributes on
special files. One of the usage examples is the XFS quota projects.
XFS has project quotas which could be attached to a directory. All new
inodes in these directories inherit project ID set on parent
directory.
The project is created from userspace by opening and calling
FS_IOC_FSSETXATTR on each inode. This is not possible for special
files such as FIFO, SOCK, BLK etc. Therefore, some inodes are left
with empty project ID. Those inodes then are not shown in the quota
accounting but still exist in the directory. This is not critical but
in the case when special files are created in the directory with
already existing project quota, these new inodes inherit extended
attributes. This creates a mix of special files with and without
attributes. Moreover, special files with attributes don't have a
possibility to become clear or change the attributes. This, in turn,
prevents userspace from re-creating quota project on these existing
files.
In addition, these new system calls allow the implementation of
additional attributes that we couldn't or didn't want to fit into the
legacy ioctls anymore"

GCC appears to have kind of fragile inlining heuristics, in the
sense that it can change whether or not it inlines something based on
optimizations. It looks like the kcov instrumentation being added (or in
this case, removed) from a function changes the optimization results,
and some functions marked "inline" are _not_ inlined. In that case,
we end up with __init code calling a function not marked __init, and we
get the build warnings I'm trying to eliminate in the coming patch that
adds __no_sanitize_coverage to __init functions:
WARNING: modpost: vmlinux: section mismatch in reference: acpi_get_enable_method+0x1c (section: .text.unlikely) -> acpi_psci_present (section: .init.text)
This problem is somewhat fragile (though using either __always_inline
or __init will deterministically solve it), but we've tripped over
this before with GCC and the solution has usually been to just use
__always_inline and move on.
For arm64 this requires forcing one ACPI function to be inlined with
__always_inline.

Pull arm64 fixes from Will Deacon:
"Two important arm64 fixes ahead of the 6.16 release.
The first fixes a regression introduced during the merge window where
the KVM UUID (which is used to advertise KVM-specific hypercalls for
things like time synchronisation in the guest) was corrupted thanks to
an endianness bug introduced when converting the code to use the
UUID_INIT() helper.
The second fixes a stack-pointer corruption issue during
context-switch which has been observed in the wild when taking a
pseudo-NMI with shadow call stack enabled.
Summary:
- Fix broken UUID value for the KVM/arm64 hypervisor SMCCC interface
- Fix stack corruption on context-switch, primarily seen on (but not
limited to) configurations with both pNMI and SCS enabled"

Mark Rutland noticed that the task parameter is ignored and
'current' is being used instead. Since this is usually
what its passed, it hasn't yet been causing problems but likely
will as the code gets more testing.
But, once this is fixed, it creates a new bug in copy_thread_gcs()
since the gcs_el_mode isn't yet set for the task before its being
checked. Move gcs_alloc_thread_stack() after the new task's
gcs_el0_mode initialization to avoid this.

Apple SoC device tree changes for v6.17
- Added the bindings and nodes for Apple SoC GPU. The driver itself
isn't ready for upstreaming yet due to rust dependencies but we're
confident that the bindings are stable at this point.
- Added a missing node for the touchbar framebuffer to Apple T2 device
trees, which is the BMC for some x86 Macs
- Fixed a W=1 warning by adding bit offsets to NVMEM node names. This
required a change to the generic NVMEM cell binding which will be part
of 6.17 through the NVMEM tree.

Support for the AX3000 SoC, from Harshit Shah <hshah@axiado.com>:
The AX3000 is a multi-core system-on-chip featuring four ARM Cortex-A53
cores, secure vault, hardware firewall, and AI acceleration engines. This
initial support enables basic bring-up of the SoC and evaluation platform
with CPU, timer, UART, and I3C functionality.
The series begins by adding the "axiado" vendor prefix and compatible
strings for the SoC and board. It then introduces the device tree files
and minimal ARCH_AXIADO platform support in arm64.

`cpu_switch_to()` and `call_on_irq_stack()` manipulate SP to change
to different stacks along with the Shadow Call Stack if it is enabled.
Those two stack changes cannot be done atomically and both functions
can be interrupted by SErrors or Debug Exceptions which, though unlikely,
is very much broken : if interrupted, we can end up with mismatched stacks
and Shadow Call Stack leading to clobbered stacks.
In `cpu_switch_to()`, it can happen when SP_EL0 points to the new task,
but x18 stills points to the old task's SCS. When the interrupt handler
tries to save the task's SCS pointer, it will save the old task
SCS pointer (x18) into the new task struct (pointed to by SP_EL0),
clobbering it.
In `call_on_irq_stack()`, it can happen when switching from the task stack
to the IRQ stack and when switching back. In both cases, we can be
interrupted when the SCS pointer points to the IRQ SCS, but SP points to
the task stack. The nested interrupt handler pushes its return addresses
on the IRQ SCS. It then detects that SP points to the task stack,
calls `call_on_irq_stack()` and clobbers the task SCS pointer with
the IRQ SCS pointer, which it will also use !
This leads to tasks returning to addresses on the wrong SCS,
or even on the IRQ SCS, triggering kernel panics via CONFIG_VMAP_STACK
or FPAC if enabled.
This is possible on a default config, but unlikely.
However, when enabling CONFIG_ARM64_PSEUDO_NMI, DAIF is unmasked and
instead the GIC is responsible for filtering what interrupts the CPU
should receive based on priority.
Given the goal of emulating NMIs, pseudo-NMIs can be received by the CPU
even in `cpu_switch_to()` and `call_on_irq_stack()`, possibly *very*
frequently depending on the system configuration and workload, leading
to unpredictable kernel panics.
Completely mask DAIF in `cpu_switch_to()` and restore it when returning.
Do the same in `call_on_irq_stack()`, but restore and mask around
the branch.
Mask DAIF even if CONFIG_SHADOW_CALL_STACK is not enabled for consistency
of behaviour between all configurations.
Introduce and use an assembly macro for saving and masking DAIF,
as the existing one saves but only masks IF.

Recent patches selecting HAVE_RELIABLE_STACKTRACE and HAVE_LIVEPATCH
added them to the end of the ARM64 Kconfig select list. Move them around
to keep this list nearly alphabetically ordered.

POR_EL0 is set to its most permissive value before setting up the
signal frame, to ensure that uaccess succeeds regardless of the
signal stack's pkey.
We are now tolerant to spurious POE faults. This means that we do
not strictly need to issue an ISB after updating POR_EL0, even when
followed by uaccess. The question is whether a fault is likely to
happen or not if the ISB is omitted; in this case the answer seems
to be no. If the regular stack is used, then it should already be
accessible. If the alternate signal stack is used, then a special
(inaccessible) pkey may be used - the assumption is that this
situation is very uncommon.
Remove the ISB to speed up the regular path - this should not have
any functional impact regardless of the scenario.

In preparation for Clang stack depth tracking for KSTACK_ERASE,
split the stackleak-specific cflags out of GCC_PLUGINS_CFLAGS into
KSTACK_ERASE_CFLAGS.

In preparation for adding Clang sanitizer coverage stack depth tracking
that can support stack depth callbacks:
- Add the new top-level CONFIG_KSTACK_ERASE option which will be
implemented either with the stackleak GCC plugin, or with the Clang
stack depth callback support.
- Rename CONFIG_GCC_PLUGIN_STACKLEAK as needed to CONFIG_KSTACK_ERASE,
but keep it for anything specific to the GCC plugin itself.
- Rename all exposed "STACKLEAK" names and files to "KSTACK_ERASE" (named
for what it does rather than what it protects against), but leave as
many of the internals alone as possible to avoid even more churn.
While here, also split "prev_lowest_stack" into CONFIG_KSTACK_ERASE_METRICS,
since that's the only place it is referenced from.
