Subject: [PATCH 0/7] Add support for GNU gold

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.

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