[PATCH 0/8 v3] KVM support for 1GB pages

[Joerg Roedel]

Hi,

this is the third version of the patches for KVM to support 1GB pages. Changes
to the last version include:

	- changed reporting of 1GB page support to userspace to use
	  SUPPORTED_CPUID ioctl
	- added support for 1GB pages to the software page walker code too

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
