Here are the patches that I applied to percpu#this_cpu_ops branch.
This branch won't be rebased and contains only the commits which
implement the new this_cpu_* ops, so that it can be pulled into other
trees without patches which make use of the operations which modify
other subsystems.

Christoph, I rearranged things a bit to make it conform better to the
overall organization.  It would be great if you can go over it once
just in case.

There are two git branches.

 git:// this_cpu_ops
 git:// for-2.6.38

Both branches won't be rebased.  this_cpu_ops contains only patches
from this series.  for-2.6.38 contains other percpu changes mostly
composed of patches which apply this_cpu_*() ops.

Thank you.
