  arm64: armv8_deprecated: Fix undef_hook mask for thumb setend (2020-04-08 18:19:20 +0100)

----------------------------------------------------------------
arm64 fixes:

- Ensure that the compiler and linker versions are aligned so that ld
  doesn't complain about not understanding a .note.gnu.property section
  (emitted when pointer authentication is enabled).

- Force -mbranch-protection=none when the feature is not enabled, in
  case a compiler may choose a different default value.

- Remove CONFIG_DEBUG_ALIGN_RODATA. It was never in defconfig and rarely
  enabled.

- Fix checking 16-bit Thumb-2 instructions checking mask in the
  emulation of the SETEND instruction (it could match the bottom half of
  a 32-bit Thumb-2 instruction).
