Linus Torvalds cd546f7ae2 Assorted arm64, ACPI and kselftest fixes for 7.1-rc2:
- 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)
