Subject: [GIT PULL] KVM updates for the 3.9 merge window



Linus,

Please pull from

git://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/kvm-3.9-1

to receive the KVM updates for the 3.9 merge window, including x86 real
mode emulation fixes, stronger memory slot interface restrictions, 
mmu_lock spinlock hold time reduction, improved handling of large 
page faults on shadow, initial APICv HW acceleration support, 
s390 channel IO based virtio, amongst others.
