I started doing this and it's a bit ridiculous.  If I split the
patches into separate trees with maintainers, I end up with a lot of
one or several liners and all that those patches do is adding __percpu
to a variable or field declaration which doesn't affect normal builds
at all.  The only conflicts I had against the current mainline is the
ones which got changed in the percpu tree by Christoph's patches.

Given the wide number of trees this will end up on and given the
triviality of each change, I think it would better to keep these in
the percpu tree.  It'll make things harder track without adding much
benefit.  If non-trivial confict ever happens, please feel free to
drop it from linux-next and let me know.

Thanks.
