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

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,
	
	Joerg
