I was going to say "no more work needed" and noticed that the series has
checkpatch errors and warns as I was running the series through
pre-commit tests.

Patches 1,2,3,8 have errors/warns based
on quick look at the log.


ERROR: need consistent spacing around '%' (ctx:WxV)
#227: FILE: tools/testing/selftests/rseq/rseq-x86.h:104:
+		RSEQ_ASM_CMP_CPU_ID(cpu_id, RSEQ_CPU_ID_OFFSET(%[rseq_abi]), %l[error1])


Will you be able to fix them and resend?
