Linus Torvalds 4ba380f616 arm64 updates for 5.5:
- On ARMv8 CPUs without hardware updates of the access flag, avoid
   failing cow_user_page() on PFN mappings if the pte is old. The patches
   introduce an arch_faults_on_old_pte() macro, defined as false on x86.
   When true, cow_user_page() makes the pte young before attempting
   __copy_from_user_inatomic().
 
 - Covert the synchronous exception handling paths in
   arch/arm64/kernel/entry.S to C.
 
 - FTRACE_WITH_REGS support for arm64.
 
 - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4
 
 - Several kselftest cases specific to arm64, together with a MAINTAINERS
   update for these files (moved to the ARM64 PORT entry).
 
 - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale
   instructions under certain conditions.
 
 - Workaround for Cortex-A57 and A72 errata where the CPU may
   speculatively execute an AT instruction and associate a VMID with the
   wrong guest page tables (corrupting the TLB).
 
 - Perf updates for arm64: additional PMU topologies on HiSilicon
   platforms, support for CCN-512 interconnect, AXI ID filtering in the
   IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2.
 
 - GICv3 optimisation to avoid a heavy barrier when accessing the
   ICC_PMR_EL1 register.
 
 - ELF HWCAP documentation updates and clean-up.
 
 - SMC calling convention conduit code clean-up.
 
 - KASLR diagnostics printed during boot
 
 - NVIDIA Carmel CPU added to the KPTI whitelist
 
 - Some arm64 mm clean-ups: use generic free_initrd_mem(), remove stale
   macro, simplify calculation in __create_pgd_mapping(), typos.
 
 - Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for
   endinanness to help with allmodconfig.

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

Pull arm64 updates from Catalin Marinas:
 "Apart from the arm64-specific bits (core arch and perf, new arm64
  selftests), it touches the generic cow_user_page() (reviewed by
  Kirill) together with a macro for x86 to preserve the existing
  behaviour on this architecture.

  Summary:

   - On ARMv8 CPUs without hardware updates of the access flag, avoid
     failing cow_user_page() on PFN mappings if the pte is old. The
     patches introduce an arch_faults_on_old_pte() macro, defined as
     false on x86. When true, cow_user_page() makes the pte young before
     attempting __copy_from_user_inatomic().

   - Covert the synchronous exception handling paths in
     arch/arm64/kernel/entry.S to C.

   - FTRACE_WITH_REGS support for arm64.

   - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4

   - Several kselftest cases specific to arm64, together with a
     MAINTAINERS update for these files (moved to the ARM64 PORT entry).

   - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale
     instructions under certain conditions.

   - Workaround for Cortex-A57 and A72 errata where the CPU may
     speculatively execute an AT instruction and associate a VMID with
     the wrong guest page tables (corrupting the TLB).

   - Perf updates for arm64: additional PMU topologies on HiSilicon
     platforms, support for CCN-512 interconnect, AXI ID filtering in
     the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2.

   - GICv3 optimisation to avoid a heavy barrier when accessing the
     ICC_PMR_EL1 register.

   - ELF HWCAP documentation updates and clean-up.

   - SMC calling convention conduit code clean-up.

   - KASLR diagnostics printed during boot
