Paolo, this needs a linux-headers update. Should I let you update
the headers in your tree and apply this patch, or can I run
update-linux-headers.sh on my x86 branch?

This patch's dependency is not even in any upstream KVM branch, so it
will take some time. For now, just apply it with the linux-headers
changes, and don't "graduate" it from x86-next to x86 until the
headers are updated.

This is okay BTW, but I'm waiting for the header file update.

This patch brings in the necessary changes from the corresponding kernel
patchset. It's included only for completeness; ideally these changes
should arrive via the standard kernel header pull.
