Pull kvm fixes from Paolo Bonzini:
 "ARM:

   - Correctly handle 'invariant' system registers for protected VMs

   - Improved handling of VNCR data aborts, including external aborts

   - Fixes for handling of FEAT_RAS for NV guests, providing a sane
     fault context during SEA injection and preventing the use of
     RASv1p1 fault injection hardware

   - Ensure that page table destruction when a VM is destroyed gives an
     opportunity to reschedule

   - Large fix to KVM's infrastructure for managing guest context loaded
     on the CPU, addressing issues where the output of AT emulation
     doesn't get reflected to the guest

   - Fix AT S12 emulation to actually perform stage-2 translation when
     necessary

   - Avoid attempting vLPI irqbypass when GICv4 has been explicitly
     disabled for a VM

   - Minor KVM + selftest fixes

  RISC-V:

   - Fix pte settings within kvm_riscv_gstage_ioremap()

   - Fix comments in kvm_riscv_check_vcpu_requests()

   - Fix stack overrun when setting vlenb via ONE_REG

  x86:

   - Use array_index_nospec() to sanitize the target vCPU ID when
     handling PV IPIs and yields as the ID is guest-controlled.

   - Drop a superfluous cpumask_empty() check when reclaiming SEV
     memory, as the common case, by far, is that at least one CPU will
     have entered the VM, and wbnoinvd_on_cpus_mask() will naturally
     handle the rare case where the set of have_run_cpus is empty.

  Selftests (not KVM):

   - Rename the is_signed_type() macro in kselftest_harness.h to
     is_signed_var() to fix a collision with linux/overflow.h. The
     collision generates compiler warnings due to the two macros having
     different meaning"
