[cc: linux-ppc, Arnd, Paul]
The patch makes identical changes to
'arch/powerpc/include/uapi/asm/errno.h' and its copy
'tools/arch/powerpc/include/uapi/asm/errno.h' first created in kernel
v4.16. Since it's the patch
hunk for the latter file which is failing on backports to < v4.16, I
would think it OK to skip
that hunk where the latter file is missing. I'd prefer to let Michael
decide the best course as
he's still reviewing the patch.
Thanks,
Tony
