[GIT PULL] arm64 updates for 7.4
From: Catalin Marinas
Date: Fri Oct 16 2026 - 10:52:11 EST
Hi Linus,
Here are the arm64 updates for 7.4. The more interesting bits are the
removal of big-endian kernel support (already marked BROKEN for some
time), preemptible this_cpu_*() operations and MPAM support for the
firmware-backed (Fb) interface. CCA (Arm's confidential compute) is
slowly trickling in with host RMI (Realm Management Interface) support
and some refactoring, including a dedicated SMCCC bus to advertise
firmware services. There are also the usual PMU updates for new hardware
and a few fixes/cleanups. More details in the tag.
I think there are some simple merge conflicts, depending on the order
you pull trees (KVM, mm), but the -next resolution is correct.
Thanks.
The following changes since commit 93f51579e7df248780214094418f205253383cc5:
Linux 7.3-rc4 (2026-09-20 13:48:15 -0700)
are available in the Git repository at:

Merge branch 'for-next/fw-rmi' into for-next/core (2026-10-15 19:09:31 +0100)
----------------------------------------------------------------
Core features:
- Remove big-endian kernel support: CONFIG_CPU_BIG_ENDIAN has depended
on BROKEN for a while, so drop the remaining code (BE hypervisor
object, BPF JIT, assembly/crypto/library routines, endianness helper
macros, selftests) and force a little-endian build
- Add preemptible this_cpu_*() operations (read/write, RMW, xchg,
cmpxchg and cmpxchg128) that no longer need to disable preemption
around the per-CPU address generation and access
- Preparation patches for implementing CONFIG_HOTPLUG_PARALLEL on
arm64
Memory management:
- Treat faults taken by EFI runtime firmware as kernel faults
- Clear PTE_WRITE for EFI_MEMORY_RO mappings (with hardware dirty state
management enabled, this is not truly read-only)
- Raise the default ARCH_MMAP_RND_BITS for 48-bit and 52-bit VA
configurations (28/26/24 bits for 4K/16K/64K pages)
- Implement clear_page[s]() using memset()
- Enable BBML2 no-abort (a.k.a. BBML3) for the NVIDIA Rigel CPU
Perf and PMU:
- Support for HiSilicon's ITS PMU
- Add support for some new events: INST_SIMD_ALU_VEC for Apple PMUs and
a cycle counter for the latest version of HiSilicon's MN PMU hardware
- A bunch of fixes to the CXL PMU driver to address pre-existing issues
from Sashiko
- Fix generation of PERF_RECORD_ITRACE_START records for SPE and ETM
drivers
- Reduce excessive stack consumption in the Marvell DDR PMU driver
- Minor driver updates and cleanups all over
Arm Confidential Compute Architecture (CCA):
- Add an Arm SMCCC bus for firmware services discovered through SMCCC
and move the TRNG and CCA guest (TSM provider) drivers onto it,
removing the dummy CCA platform device and adding a sysfs ABI for
Realm guests
- Move the Realm Service Interface (RSI) code out of arch/arm64/ into
drivers/firmware/arm_rmm/
- Add the host side of the Realm Management Interface (RMI): detect,
configure and activate the RMM, add SRO support and wrappers for the
Realm RMI commands
- Block hibernation (new arch hook in the PM core) and kexec while the
RMM is active. To be revisited in the future with proper support for
deactivation
- Handle Granule Protection Faults (GPFs) taken by the host, caused by
accesses to memory delegated to the RMM. In a future patch, the
exception table lookup will be limited to is_kdump_kernel() cases
MPAM (Memory Partitioning And Monitoring):
- Add support for the MPAM firmware-backed (Fb) interface, allowing
MSC accesses to be mediated by firmware
- Fix a list of theoretical issues with the driver (MSC access error
propagation, MBWU monitor save/restore and locking, resctrl class
handling, error interrupt restore, maximum number of PARTIDs)
- Add the mailing list and a missing file to the MAINTAINERS entry
- Document when to set arm64.nompam
Errata and CPU features:
- Add the NXP i.MX8QM/8QP workaround for the Cortex-A53 cache coherency
issue (ERR050104), using a new ARM64_CPUCAP_SOC_ERRATUM capability
type for SoC-level errata
Miscellaneous:
- Mask debug exceptions (DAIF) around the hardware breakpoint register
manipulations when called from generic kernel code
- Don't zero the SVE state buffer when the SVE state is live
- Return -EPERM instead of -EBUSY from the GCS prctl() locking
failures (matching x86), with the selftest updated. Slight ABI change
but no software deployment yet
- kselftest: fix unsound MTE fault skipping by introducing MTE-safe
memory accessors, avoid copying each signal test binary more than
once
- Update sysreg definitions (fix three enum values and two field names,
mark architecturally dropped fields as RES0) and remove the TME
transaction state check from the BRBE driver
- Fix the description of ARM64_HAS_LPA2 and remove a redundant
ID_AA64MMFR0 define
