[PATCH 0/6 v4] KVM support for 1GB pages

[Joerg Roedel <joerg.roedel@amd.com>]

Hi,

this is the forth version of the patches for KVM to support 1GB pages.
This code still only can make use of 1GB pages with nested paging
enabled. I will give the shadow paging code another debug round soon.
Please comment or consider to apply these patches.

Thanks,
