Pull kvm fixes from Paolo Bonzini:
 "These are mostly Oliver's Arm changes: lock ordering fixes for the
  vGIC, and reverts for a buggy attempt to avoid RCU stalls on large
  VMs.

  Arm:

   - Invalidate nested MMUs upon freeing the PGD to avoid WARNs when
     visiting from an MMU notifier

   - Fixes to the TLB match process and TLB invalidation range for
     managing the VCNR pseudo-TLB

   - Prevent SPE from erroneously profiling guests due to UNKNOWN reset
     values in PMSCR_EL1

   - Fix save/restore of host MDCR_EL2 to account for eagerly
     programming at vcpu_load() on VHE systems

   - Correct lock ordering when dealing with VGIC LPIs, avoiding
     scenarios where an xarray's spinlock was nested with a *raw*
     spinlock

   - Permit stage-2 read permission aborts which are possible in the
     case of NV depending on the guest hypervisor's stage-2 translation

   - Call raw_spin_unlock() instead of the internal spinlock API

   - Fix parameter ordering when assigning VBAR_EL1

   - Reverted a couple of fixes for RCU stalls when destroying a stage-2
     page table.

     There appears to be some nasty refcounting / UAF issues lurking in
     those patches and the band-aid we tried to apply didn't hold.

  s390:

   - mm fixes, including userfaultfd bug fix

  x86:

   - Sync the vTPR from the local APIC to the VMCB even when AVIC is
     active.

     This fixes a bug where host updates to the vTPR, e.g. via
     KVM_SET_LAPIC or emulation of a guest access, are lost and result
     in interrupt delivery issues in the guest"
