Linus, please pull from the repo and tag at:

git://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/kvm-3.7-1

to receive the KVM updates for the 3.7 merge windows. Highlights of the
changes for this release include support for vfio level triggered interrupts,
improved big real mode support on older Intels, a streamlines guest page table
walker, guest APIC speedups, PIO optimizations, better overcommit handling, and
read-only memory.

Shortlog and diffstat follow.
