  arm64: signal: Preserve POR_EL0 if poe_context is missing (2026-05-01 17:44:25 +0100)

----------------------------------------------------------------
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)
