All patches accepted into percpu till now are in the following branch.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git for-next

The tree is based on v2.6.37-rc5 and v2.6.37-rc5..for-next would give
21 patches.  I think most of these don't fit x86 tree but there are
several which would fit there much better.  d80aadf9 (x86: Replace
uses of current_cpu_data with this_cpu ops) and e5195e91 (x86: Use
this_cpu_inc_return for nmi counter).

As it would be beneficial to push these through -tip testing anyway,
how about the following?

* If you review and ack the x86 related bits in the series, I'll
  regenerated and add the ACKs.

* It would be better if the two commits mentioned above get routed
  through x86 tree rather than percpu tree, so I'll drop the above two
  from percpu tree and you can pull percpu into x86 and then apply
  those in x86 tree.

Thanks.
