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"

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Alexander Gordeev:
- Standardize on the __ASSEMBLER__ macro that is provided by GCC and
Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both
uapi and non-uapi headers
- Explicitly include <linux/export.h> in architecture and driver files
which contain an EXPORT_SYMBOL() and remove the include from the
files which do not contain the EXPORT_SYMBOL()
- Use the full title of "z/Architecture Principles of Operation" manual
and the name of a section where facility bits are listed
- Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
unnecessary slowing down of the build and confusing external kABI
tools that process symtypes data
- Print additional unrecoverable machine check information to make the
root cause analysis easier
- Move cmpxchg_user_key() handling to uaccess library code, since the
generated code is large anyway and there is no benefit if it is
inlined
- Fix a problem when cmpxchg_user_key() is executing a code with a
non-default key: if a system is IPL-ed with "LOAD NORMAL", and the
previous system used storage keys where the fetch-protection bit was
set for some pages, and the cmpxchg_user_key() is located within such
page, a protection exception happens
- Either the external call or emergency signal order is used to send an
IPI to a remote CPU. Use the external order only, since it is at
least as good and sometimes even better, than the emergency signal
- In case of an early crash the early program check handler prints more
or less random value of the last breaking event address, since it is
not initialized properly. Copy the last breaking event address from
the lowcore to pt_regs to address this
- During STP synchronization check udelay() can not be used, since the
first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
return a non-monotonic time. Instead, busy-loop on other CPUs, while
the the first CPU actually handles the synchronization operation
- When debugging the early kernel boot using QEMU with the -S flag and
GDB attached, skip the decompressor and start directly in kernel
- Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
Principles of Operation" manual
- Remove the in-kernel time steering support in favour of the new s390
PTP driver, which allows the kernel clock steered more precisely
- Remove a possible false-positive warning in pte_free_defer(), which
could be triggered in a valid case KVM guest process is initializing

In order to support Clang's stack depth tracking (for Linux's kstack_erase
feature), the coverage sanitizer needed to be disabled for __init (and
__head) section code. Doing this universally (i.e. for GCC too) created
a number of unexpected problems, ranging from changes to inlining logic
to failures to DCE code on earlier GCC versions.
Since this change is only needed for Clang, specialize it so that GCC
doesn't see the change as it isn't needed there (the GCC implementation
of kstack_erase uses a GCC plugin that removes stack depth tracking
instrumentation from __init sections during a late pass in the IR).
Successfully build and boot tested with GCC 12 and Clang 22.

Update the I2C frequency table to match the recommended values
specified in the I2C hardware programming guide. In the current IPQ5424
configuration where 32MHz is the source clock, the I2C bus frequencies do
not meet expectations—for instance, 363KHz is achieved instead of the
expected 400KHz.

Calling dma_sync_*() on a buffer from dma_alloc_coherent() is pointless.

For controllers that has an internal software reset, make the reset
property optional. This provides and option to use I2C in systems
that choose to restrict reset control from Linux or not to implement
the ACPI _RST method.
Internal reset was not required when the reset control was mandatory.
But on platforms where the resets are outside the control of Linux,
this had to be implemented by just returning success from BPMP or with
an empty _RST method in the ACPI table, basically ignoring the reset.
While the internal reset is not identical to the hard reset of the
controller, this will reset all the internal state of the controller
including FIFOs. This may slightly alter the behaviour in systems
which were ignoring the reset but it should not cause any functional
difference since all the required I2C registers are configured after
this reset, just as in boot. Considering that this sequence is hit
during the boot or during the I2C recovery path from an error, the
internal reset provides a better alternative than just ignoring the
reset.

`i2c_*_dma_safe_msg_buf` APIs operate on a `struct i2c_msg`.
The get operation make sure the I2C buffer is DMA'able according to its
buffer length, or if the memory use is DMA coherent for example and
return a valid pointer for safe DMA access to be used.
The put operation release the pointer.
Prefer using generic API's than relying on private tests.

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 timer cleanups from Thomas Gleixner:
"A treewide cleanup of struct cycle_counter const annotations.
The initial idea of making them const was correct as they were
seperate instances. When they got embedded into larger data
structures, which are even modified by the callback this got moot. The
only reason why this went unnoticed is that the required
container_of() casts the const attribute forcefully away.
Stop pretending that it is const"

Pull interrupt chip driver updates from Thomas Gleixner:
- Add support of forced affinity setting to yet offline CPUs for the
MIPS-GIC to ensure that the affinity of per CPU interrupts can be set
during the early bringup phase of a secondary CPU in the hotplug code
before the CPU is set online and interrupts are enabled
- Add support for the MIPS (RISC-V !?!?) P8700 SoC in the ACLINT_SSWI
interrupt chip
- Make the interrupt routing to RISV-V harts specification compliant so
it supports arbitrary hart indices
- Add a command line parameter and related handling to disable the
generic RISCV IMSIC mechanism on platforms which use a trap-emulated
IMSIC. Unfortunatly this is required because there is no mechanism
available to discover this programatically.
- Enable wakeup sources on the Renesas RZV2H driver
- Convert interrupt chip drivers, which use a open coded variant of
msi_create_parent_irq_domain() to use the new functionality
- Convert interrupt chip drivers, which use the old style two level
implementation of MSI support over to the MSI parent mechanism to
prepare for removing at least one of the three PCI/MSI backend
variants.
- The usual cleanups and improvements all over the place

Pull irq updates from Thomas Gleixner:
- Prevent a interrupt migration related live lock in handle_edge_irq()
If the interrupt affinity is moved to a new target CPU and the
interrupt is currently handled on the previous target CPU for edge
type interrupts the handler might get stuck on the previous target
for a long time, which causes both involved CPUs to waste cycles and
eventually run into a soft-lockup situation.
Solve this by checking whether the interrupt is redirected to a new
target CPU and if the interrupt is handled on that new target CPU,
busy wait for completion instead of masking it and sending the
pending but which would cause the old CPU to re-run the handler and
in the worst case repeating this excercise for a long time.
This only works on architectures which use single CPU interrupt
targets, but that's so far the only ones where this behaviour has
been observed.
- Add a kunit test for interrupt disable depth counts
The nested interrupt disable depth has been an issue in the past
especially vs. free_irq(), interrupt shutdown and CPU hotplug and
their interactions. The test exercises the combinations of these
scenarios and checks for correctness.
