    Pull KVM fixes from Radim Krčmář:
     "PPC:
    
       - Close a hole which could possibly lead to the host timebase getting
         out of sync.
    
       - Three fixes relating to PTEs and TLB entries for radix guests.
    
       - Fix a bug which could lead to an interrupt never getting delivered
         to the guest, if it is pending for a guest vCPU when the vCPU gets
         offlined.
    
      s390:
    
       - Fix false negatives in VSIE validity check (Cc stable)
    
      x86:
    
       - Fix time drift of VMX preemption timer when a guest uses LAPIC
         timer in periodic mode (Cc stable)
    
       - Unconditionally expose CPUID.IA32_ARCH_CAPABILITIES to allow
         migration from hosts that don't need retpoline mitigation (Cc
         stable)
    
       - Fix guest crashes on reboot by properly coupling CR4.OSXSAVE and
         CPUID.OSXSAVE (Cc stable)
    
       - Report correct RIP after Hyper-V hypercall #UD (introduced in
         -rc6)"
