Subject: [PATCH][PARAVIRT] Eliminate unnecessary CR3 read in TLB flush

This patch eliminates the CR3 read (which would cause a VM exit) in the TLB
flush path.  The patch is based on Ingo Molnar's paravirt series.

    

This change could be just done generically for the native architecture, couldn't 
it?
  

Sure.  It adds a few more cycles onto native though (two memory reads, 
and some math).  How does the following look?
