Pull arm64 updates from Catalin Marinas:
"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.

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"

Merge v7.2-rc1 into drm-rust-next to start the next cycle.

Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.

If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

Sync up with mainline to pull in a fix to IMS PCU driver and other
enhancements.

mshv: Add conditional VMBus dependency

When the VMBus driver is not part of the kernel (CONFIG_HYPERV_VMBUS=n),
the MSHV root driver fails to link:

ERROR: modpost: "hv_vmbus_exists" [drivers/hv/msh

mshv: Add conditional VMBus dependency

When the VMBus driver is not part of the kernel (CONFIG_HYPERV_VMBUS=n),
the MSHV root driver fails to link:

ERROR: modpost: "hv_vmbus_exists" [drivers/hv/mshv_root.ko] undefined!

Fix this while meeting these requirements:
* It must be possible to include the MSHV root driver without the
VMBus driver. In such case, the MSHV root driver can be built-in
to the kernel image, or it can be built as a separate module.
* If both the MSHV root driver and the VMBus driver are present, the
MSHV root driver and VMBus driver can both be built-in, or they can
both be separate modules. Or the MSHV root driver can be a module
while the VMBus driver can be built-in, but the reverse is
disallowed. Regardless of the build choices, the VMBus driver must
be loaded before the MSHV driver in order for the SynIC to be
managed properly (see comments in the MSHV SynIC code).

The fix has two parts:
* Add a Kconfig entry for MSHV_ROOT to depend on HYPERV_VMBUS if
HYPERV_VMBUS is present. The entry disallows MSHV_ROOT being
built-in when HYPERV_VMBUS is a module, but without requiring that
HYPERV_VMBUS be built.
* Add a stub implementation of hv_vmbus_exists() for when the
VMBus driver is not present so that the MSHV root driver has
no module dependency on VMBus. When the VMBus driver *is*
present, the module dependency ensures that the VMBus driver
loads first when both are built as modules.

Existing code ensures that the VMBus driver loads first if it is
built-in. The VMBus driver uses subsys_initcall(), which is
initcall level 4. The MSHV root driver uses module_init(), which
becomes device_init() when built-in, and device_init() is
initcall level 6.
