Merge tag 'arm64-fixes' of git://git./linux/kernel/git/arm64/linux

Pull arm64 fixes from Catalin Marinas:

 - Clean-ups following the merging window: remove unused variable,
   duplicate includes, superfluous barrier, move some inline asm to
   separate functions.

 - Disable top-byte-ignore on kernel code addresses with KASAN/MTE
   enabled (already done when MTE is disabled).

 - Fix ARCH_LOW_ADDRESS_LIMIT definition with CONFIG_ZONE_DMA disabled.

 - Compiler/linker flags: link with "-z norelno", discard .eh_frame_hdr
   instead of --no-eh-frame-hdr.
