Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- 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).
