Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Avoid writing an uninitialised stack variable to POR_EL0 on sigreturn
if the poe_context record is absent
- Reserve one more page for the early 4K-page kernel mapping to cover
the extra [_text, _stext) split introduced by the non-executable
read-only mapping
- Force the arch_local_irq_*() wrappers to be __always_inline so that
noinstr entry and idle paths cannot call out-of-line, instrumentable
copies
- Fix potential sign extension in the arm64 SCS unwinder's DWARF
advance_loc4 decoding
- Tolerate arm64 ACPI platforms with only WFI and no deeper PSCI idle
states, restoring cpuidle registration on such systems
- Include the UAPI <asm/ptrace.h> header in the arm64 GCS libc test
rather than carrying a duplicate struct user_gcs definition (the
original #ifdef NT_ARM_GCS was wrong to cover the structure
definition as it would be masked out if the toolchain defined it)
