Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Paolo Bonzini:
"Two very simple bugfixes, affecting all supported architectures"
[ Two? There's three commits in here. Oh well, I guess Paolo didn't
count the preparatory symbol export ]
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
KVM: correct null pid check in kvm_vcpu_yield_to()
KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn()
mm: export symbol dependencies of is_zero_pfn()
