Please remove this tag - the only thing I suggested was to drop part
of the original patch.

[PATCH v2] arm64: vdso: remove commas between macro name and arguments

2021-04-16 Thread Jian Cai
LLVM's integrated assembler does not support using commas separating
the name and arguments in .macro. However, only spaces are used in the
manual page. This replaces commas between macro names and the subsequent
arguments with space in calls to clock_gettime_return to make it
compatible with IAS.

Changes v1 -> v2:
  Keep the comma in the macro definition to be consistent with other
  definitions.
