  KVM: MIPS/VZ: Fix build error caused by 'kvm_run' cleanup (2020-08-11 07:19:41 -0400)

----------------------------------------------------------------
PPC:
* Improvements and bugfixes for secure VM support, giving reduced startup
  time and memory hotplug support.
* Locking fixes in nested KVM code
* Increase number of guests supported by HV KVM to 4094
* Preliminary POWER10 support

ARM:
* Split the VHE and nVHE hypervisor code bases, build the EL2 code
  separately, allowing for the VHE code to now be built with instrumentation
* Level-based TLB invalidation support
* Restructure of the vcpu register storage to accomodate the NV code
* Pointer Authentication available for guests on nVHE hosts
* Simplification of the system register table parsing
* MMU cleanups and fixes
* A number of post-32bit cleanups and other fixes

MIPS:
* compilation fixes

x86:
* bugfixes
* support for the SERIALIZE instruction
