Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull KVM updates from Paolo Bonzini:
 "ARM:
   - data abort report and injection
   - steal time support
   - GICv4 performance improvements
   - vgic ITS emulation fixes
   - simplify FWB handling
   - enable halt polling counters
   - make the emulated timer PREEMPT_RT compliant

  s390:
   - small fixes and cleanups
   - selftest improvements
   - yield improvements

  PPC:
   - add capability to tell userspace whether we can single-step the
     guest
   - improve the allocation of XIVE virtual processor IDs
   - rewrite interrupt synthesis code to deliver interrupts in virtual
     mode when appropriate.
   - minor cleanups and improvements.

  x86:
   - XSAVES support for AMD
   - more accurate report of nested guest TSC to the nested hypervisor
   - retpoline optimizations
   - support for nested 5-level page tables
   - PMU virtualization optimizations, and improved support for nested
     PMU virtualization
   - correct latching of INITs for nested virtualization
   - IOAPIC optimization
   - TSX_CTRL virtualization for more TAA happiness
   - improved allocation and flushing of SEV ASIDs
   - many bugfixes and cleanups"
