#     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).
#
