2.5.41-mm2

. The per-cpu pages patches continue to disgrace themselves.  Improvements
  in some microbenchmarks range from moderate (2%) to stunning (60%) but
  we're seeing a consistent few-percent regression in tests which perform
  networking to localhost.  Heads continue to be scratched.  This is
  irritating because that code is supposed to be the foundation for a page
  reservation API which fixes the radix-tree and pte_chain allocation failure
  problems.

  Ingo's original per-cpu-pages patch was said to be mainly beneficial for
  web-serving type things, but no specweb testing has been possible for a
  week or two due to oopses in the timer code.

. David McCracken's shared pagetable implementation is included - it is
  configurable on or off under the "Processor type and features" menu.

. The swappiness control code seems to be working well.
