Linus Torvalds 44fc84337b arm64 updates for 6.19:
Core features:
 
  - Basic Arm MPAM (Memory system resource Partitioning And Monitoring)
    driver under drivers/resctrl/ which makes use of the fs/rectrl/ API
 
 Perf and PMU:
 
  - Avoid cycle counter on multi-threaded CPUs
 
  - Extend CSPMU device probing and add additional filtering support for
    NVIDIA implementations
 
  - Add support for the PMUs on the NoC S3 interconnect
 
  - Add additional compatible strings for new Cortex and C1 CPUs
 
  - Add support for data source filtering to the SPE driver
 
  - Add support for i.MX8QM and "DB" PMU in the imx PMU driver
 
 Memory managemennt:
 
  - Avoid broadcast TLBI if page reused in write fault
 
  - Elide TLB invalidation if the old PTE was not valid
 
  - Drop redundant cpu_set_*_tcr_t0sz() macros
 
  - Propagate pgtable_alloc() errors outside of __create_pgd_mapping()
 
  - Propagate return value from __change_memory_common()
 
 ACPI and EFI:
 
  - Call EFI runtime services without disabling preemption
 
  - Remove unused ACPI function
 
 Miscellaneous:
 
  - ptrace support to disable streaming on SME-only systems
 
  - Improve sysreg generation to include a 'Prefix' descriptor
 
  - Replace __ASSEMBLY__ with __ASSEMBLER__
 
  - Align register dumps in the kselftest zt-test
 
  - Remove some no longer used macros/functions
 
  - Various spelling corrections

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

Pull arm64 updates from Catalin Marinas:
 "These are the arm64 updates for 6.19.

  The biggest part is the Arm MPAM driver under drivers/resctrl/.
  There's a patch touching mm/ to handle spurious faults for huge pmd
  (similar to the pte version). The corresponding arm64 part allows us
  to avoid the TLB maintenance if a (huge) page is reused after a write
  fault. There's EFI refactoring to allow runtime services with
  preemption enabled and the rest is the usual perf/PMU updates and
  several cleanups/typos.

  Summary:

  Core features:

   - Basic Arm MPAM (Memory system resource Partitioning And Monitoring)
     driver under drivers/resctrl/ which makes use of the fs/rectrl/ API

  Perf and PMU:

   - Avoid cycle counter on multi-threaded CPUs

   - Extend CSPMU device probing and add additional filtering support
     for NVIDIA implementations

   - Add support for the PMUs on the NoC S3 interconnect

   - Add additional compatible strings for new Cortex and C1 CPUs

   - Add support for data source filtering to the SPE driver

   - Add support for i.MX8QM and "DB" PMU in the imx PMU driver
