These patches add macros for detecting the linker name and version,
and apply fixes and workarounds needed to link the arm64 kernel with
GNU gold.

Changes since v1:
  - moved LD_DEAD_CODE_DATA_ELIMINATION fixes to the beginning of the
    patch set and removed mentions of gold
  - renamed ld-if-name-version to __ld-ifversion for consistency
  - cleaned up the erratum changes in arch/arm64/Makefile

Sami Tolvanen (7):
  kbuild: fix LD_DEAD_CODE_DATA_ELIMINATION
  arm64: keep .altinstructions and .altinstr_replacement
  kbuild: add ld-name macro
  kbuild: add __ld-ifversion and linker-specific macros
  arm64: fix -m for GNU gold
  arm64: explicitly pass --no-fix-cortex-a53-843419 to GNU gold
  arm64: add a workaround for GNU gold with ARM64_MODULE_PLTS
