Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Paolo Bonzini:
"PPC changes will come next week.
- s390: Support for runtime instrumentation within guests, support of
248 VCPUs.
- ARM: rewrite of the arm64 world switch in C, support for 16-bit VM
identifiers. Performance counter virtualization missed the boat.
- x86: Support for more Hyper-V features (synthetic interrupt
controller), MMU cleanups"
