    Linus Torvalds authored
    Pull KVM updates from Radim Krčmář:
       - icache invalidation optimizations, improving VM startup time
       - support for forwarded level-triggered interrupts, improving
         performance for timers and passthrough platform devices
       - a small fix for power-management notifiers, and some cosmetic
       - add MMIO emulation for vector loads and stores
       - allow HPT guests to run on a radix host on POWER9 v2.2 CPUs without
         requiring the complex thread synchronization of older CPU versions
       - improve the handling of escalation interrupts with the XIVE
         interrupt controller
       - support decrement register migration
       - various cleanups and bugfixes.
       - Cornelia Huck passed maintainership to Janosch Frank
       - exitless interrupts for emulated devices
       - cleanup of cpuflag handling
       - kvm_stat counter improvements
       - VSIE improvements
       - mm cleanup
       - hypervisor part of SEV
       - UMIP, RDPID, and MSR_SMI_COUNT emulation
       - paravirtualized TLB shootdown using the new KVM_VCPU_PREEMPTED bit
       - allow guests to see TOPOEXT, GFNI, VAES, VPCLMULQDQ, and more
         AVX512 features
       - show vcpu id in its anonymous inode name
       - many fixes and cleanups
       - per-VCPU MSR bitmaps (already merged through x86/pti branch)
       - stable KVM clock when nesting on Hyper-V (merged through
