Subject: [GIT PULL] arm64 updates for 6.18

Hi Linus,

[sending this early as I'm fishing on Monday]

Please pull this wad of arm64 changes for 6.18. 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.

We've only had a couple of trivial conflicts show up in -next:

  * The fs-next tree has taken clone3() support for shadow stacks and
    this gives rise to a simple context conflict in our asm/gcs.h.
    There's been some late ABI feedback from the glibc community,
    however, so maybe Christian will end up dropping the patches [1].

  * The kbuild tree has removed the tautological dependency that
    CONFIG_CPU_BIG_ENDIAN has on the assembler version. However, we've
    extended that to make it depend on BROKEN in anticipation of
    dropping support altogether.

I've already got a handful of minor fixes to go on top but I'll send
those separately once they've had a chance to sit in -next.

Summary in the tag.

Cheers,

Will

  arm64: cpufeature: Remove duplicate asm/mmu.h header (2025-09-24 16:44:44 +0100)

----------------------------------------------------------------
arm64 updates for 6.18

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.
