This is now applied, after modifying according to review comments.

[PATCH 0/4] cr4 optimizations for vmx/ept

2009-12-07 Thread Avi Kivity 
When ept is enabled, we aren't particularly interested in cr4.pge, so allow
the guest to own it.  This improves performance in vmap() intensive loads.

Avi Kivity (4):
  KVM: VMX: Move some cr[04] related constants to vmx.c
  KVM: Add accessor for reading cr4 (or some bits of cr4)
  KVM: VMX: Make guest cr4 mask more conservative
  KVM: VMX: When using ept, allow the guest to own cr4.pge
