  arm64: Move PSTATE.TCO setting to separate functions (2021-01-07 11:39:01 +0000)

arm64 fixes:

- 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.
