2.5.53-mm1

. Collapsed all the shared pagetable patches into a single patch, so
  it is readable now.  Also made it selectable in config again.

  It is unlikely that the shared pagetable code will be merged.

. A patch which fixes the run-child-first-after-fork logic.  This 
  supposedly will provide benefits when the child quickly exec's a
  new program, but I'm not able to measure much difference at all.  It
  would be interesting if anyone can find a workload which likes this.

  Last time we tried this, /bin/bash broke...

  This patch is much more intrusive than it needs to be - it ended up
  being a great chase against various scheduler startup bogons.  Not
  sure that it improves things much, actually.

  It will break non-ia32 kernels in its present form.
