Pull kvm fixes from Paolo Bonzini:
 "arm64:

   - Add the pKVM side of the workaround for ARM's erratum 4193714,
     provided that the EL3 firmware does its part of the job. KVM will
     refuse to initialise otherwise

   - Correctly handle 52bit VAs for guest EL2 stage-1 translations when
     running under NV with E2H==0

   - Correctly deal with permission faults in guest_memfd memslots

   - Fix the steal-time selftest after the infrastructure was reworked

   - Make sure the host cannot pass a non-sensical clock update to the
     EL2 tracing infrastructure

   - Appoint Steffen Eiden as a reviewer in anticipation of the KVM/s390
     ability to run arm64 guests, which will inevitably lead to arm64
     code being directly used on s390

   - Make sure that EL2 is configured with both exception entry and exit
     being Context Synchronization Events

   - Handle the current vcpu being NULL on EL2 panic

   - Fix the selftest_vcpu memcache being empty at the point of donation
     or sharing

   - Check that the memcache has enough capacity before engaging on the
     share/donate path

   - Fix __deactivate_fgt() to use its parameter rather than a variable
     in the macro context

  s390:

   - Fix array overrun with large amounts of PCI devices

  x86:

   - Never use L0's PAUSE loop exiting while L2 is running, since it's
     unlikely that a nested guest will help solving the hypervisor's
     spinlock contention

   - Fix emulation of MOVNTDQA

   - Fix typo in Xen hypercall tracepoint

   - Add back an optimization that was left behind when recently fixing
     a bug

   - Add module parameter to disable CET, whose implementation seems to
     have issues. For now it remains enabled by default

  Generic:

   - Reject offset causing an unsigned overflow in kvm_reset_dirty_gfn()

  Documentation:

   - Update stale links

  Selftests:

   - Fix guest_memfd_test with host page size > guest page size"
