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
