Sorry for the late reply. I asked for a leave yesterday.
asm/perf_regs.h is a new added file in the patch #1,
the patch link is:
https://lore.kernel.org/patchwork/patch/1375477/
the commit is:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/mips/include/uapi/asm/perf_regs.h?id=1ddc96bd42da
So we should build patch #2 based on patch #1.
Thanks,
Tiezhu
