Merge tag 'kvm-4.15-2' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Radim Krčmář:
"Trimmed second batch of KVM changes for Linux 4.15:
- GICv4 Support for KVM/ARM
- re-introduce support for CPUs without virtual NMI (cc stable) and
allow testing of KVM without virtual NMI on available CPUs
- fix long-standing performance issues with assigned devices on AMD
(cc stable)"
