Right, but it should be a separate patch.

Takuya, since you are going to send another version of this series, can
you also:

1) move this patch either to the beginning or to the end

2) include "KVM: x86: always set accessed bit in shadow PTEs", also near
the beginning of the series?

Thanks!

Paolo
