Just trying to apply this patch, it won't apply to mainline because it's
based upon the bleeding edge of kernel development, rather than what's
currently in mainline. If we're going to fix this in current mainline
and previous stable versions, the patch needs to be against that, not
linux-next.
Could you re-generate against an -rc kernel please?
