Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Radim Krčmář:
"PPC:
- Fix a bug causing occasional machine check exceptions on POWER8
hosts (introduced in 4.16-rc1)
x86:
- Fix a guest crashing regression with nested VMX and restricted
guest (introduced in 4.16-rc1)
- Fix dependency check for pv tlb flush (the wrong dependency that
effectively disabled the feature was added in 4.16-rc4, the
original feature in 4.16-rc1, so it got decent testing)"
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
