I'd prefer percpu things going through percpu tree, if for nothing
else for git history's sake, but I don't think it really matters.  The
series is spread all over the place anyway.  As long as each
maintainer is properly alerted about the changes, it should be okay.
Please let me know whether you agree with the changes currently queued
in percpu#for-next.  I'll update the tree with your Acked-by's and
freeze it.

Thanks.
