Support for GB pages in KVM

Hi,

this patchset extends the KVM MMU implementation to support 1GB pages as
supported by AMD family 16 processors. These patches enable support for
1 GB pages with Nested Paging. Support for these pages in the shadow
paging code was also developed but does not run stable yet. The patch
for shadow-paging support is not included in this series and will be
sent out seperatly.
