Pull arm64 updates from Will Deacon:
"There's a reasonable amount of stuff here, including a bunch of
updates to the perf PMU drivers and some MPAM updates to expose the
memory bandwidth counters via resctrl.

On the architecture side, some highlights include support for BBML3
and steps towards support for an architectural NMI solution, all
wrapped up in a web of fixes for latent issues identified by Sashiko.

ACPI:

- Combine reads of AMU counters into a single FFH feedback counter op

Confidential computing:

- Fix smp_processor_id() in preemptible context when retrieving an
attestation token inside a realm

- Convert pKVM over to a "CC platform"

- Clean-up our SWIOTLB configuration in preparation for reworking the
handling of encrypted/decryped DMA buffers in the dma-mapping tree

CPU errata handling:

- Work around broken device memory ordering on NVIDIA Olympus cores

- Fix broken 'nospectre_bhb' command-line option

- Select the idle loop backend instruction on the command-line

CPU features:

- Replace our BBML2-noabort feature with the new architectural BBML3
feature

- Disable in-kernel BTI for recent versions of Clang due to issues
with livepatch that are still being investigated

- Clean-up documentation describing which ID register fields are
exposed to userspace

Interrupts:

- Preliminary work towards supporting FEAT_NMI, which cleans up our
IRQ entry code and fixes some latent issues with pseudo-NMI

- Support for an SDEI backend to trigger an NMI backtrace

Memory management:

- Treat all devices as coherent when CLIDR_EL1.LoC == 0

- Fix no-map handling of sub-page-sized regions

- Second attempt at unmapping the linear aliases of the kernel data
and bss sections

- Fix EFI runtime calls when software-PAN is enabled

Miscellaneous:

- Add Mark Rutland as a reviewer!

- Tidy-up our futex cmpxchg logic when using the new LSUI
instructions

- Drop the requirement on DYNAMIC_FTRACE_WITH_CALL_OPS when
selecting HAVE_DYNAMIC_FTRACE_WITH_DIRECT_CALLS

- Fix a false-positive KCSCAN splat in the delay loop

- Use a portable typedef for 128-bit scalar types in our UAPI headers

- Non-critical fixes for Sashiko reports all over

MPAM:

- Hook MPAM memory bandwidth counters into resctrl's counter
assignment interface

- Fix a quirk in the MPAM bandwidth counting on Nvidia T241 so that
it also applies to 63 bit counters

Perf:

- Workarounds for hardware issues in the CMN-S3 PMU (Graviton 5) and
CPU PMU (NVIDIA Olympus again!)

- Add support for the DDR PMU on Marvell CN20K SoCs

- Add support for Picoheart implementations of the DCW PCIe PMU

- Add support for Channel/Rank/Bank filtering in the CXL PMU driver

- Add support for 64-bit counters in the CSPMU device

- Add support for revision 2 of the CMN S3 PMU

Ptrace:

- Fix a decade-old bug in our handling of seccomp and tracing on
syscall entry

- Fix regset handling for inactive SVE and SSVE registers

Selftests

- Add some tests for the decade-old bug that we just tried to fix in
our syscall entry path

- Fix SVE test crash on SME-only CPUs"

drivers/firmware: add SDEI cross-CPU NMI service for arm64

Deliver an NMI-like event to an interrupt-masked arm64 CPU via the
standard SDEI software-signalled event (event 0), without the pseudo-NMI
hot-path cost: register a handler for event 0 and poke a target with
sdei_event_signal(0, mpidr).

First user is arch_trigger_cpumask_backtrace() (sysrq-l, RCU stalls,
hung-task/soft-lockup dumps), which otherwise rides an IPI that can't
reach a masked CPU. Falls back to the IPI path when SDEI is absent; no
watchdog backend yet, so the stock detector is untouched.

Samsung SoC drivers for v6.15

1. Add support for Exynos USI v1 serial engines. Drivers already
supported newer IP blocks - USI v2 - present in Exynos850 and newer.
A bit older ARM64 designs, like Exynos8895 use older USI v1 block.

2. Add Exynos ACPM (Alive Clock and Power Manager) protocol driver
for Google GS101 SoC. ACPM protocol allows communication between the
power management firmware and other embedded processors.

firmware: add Exynos ACPM protocol driver

Alive Clock and Power Manager (ACPM) Message Protocol is defined for
the purpose of communication between the ACPM firmware and masters
(AP, AOC, ...). ACPM firmware operates on the Active Power Management
(APM) module that handles overall power activities.

ACPM and masters regard each other as independent hardware component and
communicate with each other using mailbox messages and shared memory.

This protocol driver provides the interface for all the client drivers
making use of the features offered by the APM. Add ACPM protocol support.

firmware: thead: Add AON firmware protocol driver

The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON)
firmware to manage power, clock, and other system resources [1]. This
patch introduces a driver implementing the AON firmware protocol,
allowing the Linux kernel to communicate with the firmware via mailbox
channels. Through an RPC-based interface, the kernel can initiate power
state transitions, update resource configurations, and perform other
AON-related tasks.
