Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fix from Paolo Bonzini:
"A simple fix. I'm sending it before the merge window, because it

kvm/next branch that is destined for 4.5"
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
kvm: x86: only channel 0 of the i8254 is linked to the HPET
