Linus Torvalds feafee2845 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.
