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).
