Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:
"There's good stuff across the board, including some nice mm
improvements for CPUs with the 'noabort' BBML2 feature and a clever
patch to allow ptdump to play nicely with block mappings in the
vmalloc area.

Confidential computing:

- Add support for accepting secrets from firmware (e.g. ACPI CCEL)
and mapping them with appropriate attributes.

CPU features:

- Advertise atomic floating-point instructions to userspace

- Extend Spectre workarounds to cover additional Arm CPU variants

- Extend list of CPUs that support break-before-make level 2 and
guarantee not to generate TLB conflict aborts for changes of
mapping granularity (BBML2_NOABORT)

- Add GCS support to our uprobes implementation.

Documentation:

- Remove bogus SME documentation concerning register state when
entering/exiting streaming mode.

Entry code:

- Switch over to the generic IRQ entry code (GENERIC_IRQ_ENTRY)

- Micro-optimise syscall entry path with a compiler branch hint.

Memory management:

- Enable huge mappings in vmalloc space even when kernel page-table
dumping is enabled

- Tidy up the types used in our early MMU setup code

- Rework rodata= for closer parity with the behaviour on x86

- For CPUs implementing BBML2_NOABORT, utilise block mappings in the
linear map even when rodata= applies to virtual aliases

- Don't re-allocate the virtual region between '_text' and '_stext',
as doing so confused tools parsing /proc/vmcore.

Miscellaneous:

- Clean-up Kconfig menuconfig text for architecture features

- Avoid redundant bitmap_empty() during determination of supported
SME vector lengths

- Re-enable warnings when building the 32-bit vDSO object

- Avoid breaking our eggs at the wrong end.

Perf and PMUs:

- Support for v3 of the Hisilicon L3C PMU

- Support for Hisilicon's MN and NoC PMUs

- Support for Fujitsu's Uncore PMU

- Support for SPE's extended event filtering feature

- Preparatory work to enable data source filtering in SPE

- Support for multiple lanes in the DWC PCIe PMU

- Support for i.MX94 in the IMX DDR PMU driver

- MAINTAINERS update (Thank you, Yicong)

- Minor driver fixes (PERF_IDX2OFF() overflow, CMN register offsets).

Selftests:

- Add basic LSFE check to the existing hwcaps test

- Support nolibc in GCS tests

- Extend SVE ptrace test to pass unsupported regsets and invalid
vector lengths

- Minor cleanups (typos, cosmetic changes).

System registers:

- Fix ID_PFR1_EL1 definition

- Fix incorrect signedness of some fields in ID_AA64MMFR4_EL1

- Sync TCR_EL1 definition with the latest Arm ARM (L.b)

- Be stricter about the input fed into our AWK sysreg generator
script

- Typo fixes and removal of redundant definitions.

ACPI, EFI and PSCI:

- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree

- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls

- Fix a node refcount imbalance in the PSCI device-tree code.

CPU Features:

- Ensure register sanitisation is applied to fields in ID_AA64MMFR4

- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
guests can reliably query the underlying CPU types from the VMM

- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code"

kselftest/arm64/gcs/basic-gcs: Respect parent directory CFLAGS

basic-gcs has it's own make rule to handle the special compiler
invocation to build against nolibc. This rule does not respect the
$(CFLAGS) passed by the Makefile from the parent directory.
However these $(CFLAGS) set up the include path to include the UAPI
headers from the current kernel.
Due to this the asm/hwcap.h header is used from the toolchain instead of
the UAPI and the definition of HWCAP_GCS is not found.

Restructure the rule for basic-gcs to respect the $(CFLAGS).
Also drop those options which are already provided by $(CFLAGS).

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:

- Support for running Linux in a protected VM under the Arm
Confidential Compute Architecture (CCA)

- Guarded Control Stack user-space support. Current patches follow the
x86 ABI of implicitly creating a shadow stack on clone(). Subsequent
patches (already on the list) will add support for clone3() allowing
finer-grained control of the shadow stack size and placement from
libc

- AT_HWCAP3 support (not running out of HWCAP2 bits yet but we are
getting close with the upcoming dpISA support)

- Other arch features:

- In-kernel use of the memcpy instructions, FEAT_MOPS (previously
only exposed to user; uaccess support not merged yet)

- MTE: hugetlbfs support and the corresponding kselftests

- Optimise CRC32 using the PMULL instructions

- Support for FEAT_HAFT enabling ARCH_HAS_NONLEAF_PMD_YOUNG

- Optimise the kernel TLB flushing to use the range operations

- POE/pkey (permission overlays): further cleanups after bringing
the signal handler in line with the x86 behaviour for 6.12

- arm64 perf updates:

- Support for the NXP i.MX91 PMU in the existing IMX driver

- Support for Ampere SoCs in the Designware PCIe PMU driver

- Support for Marvell's 'PEM' PCIe PMU present in the 'Odyssey' SoC

- Support for Samsung's 'Mongoose' CPU PMU

- Support for PMUv3.9 finer-grained userspace counter access
control

- Switch back to platform_driver::remove() now that it returns
'void'

- Add some missing events for the CXL PMU driver

- Miscellaneous arm64 fixes/cleanups:

- Page table accessors cleanup: type updates, drop unused macros,
reorganise arch_make_huge_pte() and clean up pte_mkcont(), sanity
check addresses before runtime P4D/PUD folding

- Command line override for ID_AA64MMFR0_EL1.ECV (advertising the
FEAT_ECV for the generic timers) allowing Linux to boot with
firmware deployments that don't set SCTLR_EL3.ECVEn

- ACPI/arm64: tighten the check for the array of platform timer
structures and adjust the error handling procedure in
gtdt_parse_timer_block()

- Optimise the cache flush for the uprobes xol slot (skip if no
change) and other uprobes/kprobes cleanups

- Fix the context switching of tpidrro_el0 when kpti is enabled

- Dynamic shadow call stack fixes

- Sysreg updates

- Various arm64 kselftest improvements

Add trivial assembly programs which give themselves the appropriate

by generating signals on the non-permitted instructions. Not using libc
minimises the interaction with any policy set for the system but we skip on
failure to get the permissions in case the system is locked down to make
them inaccessible.
