  KVM: SVM: Move GHCB unmapping to fix RCU warning (2021-05-07 06:06:23 -0400)

Thomas Gleixner and Michael Ellerman had some KVM changes in their
late merge window pull requests, but there are no conflicts.

* Lots of bug fixes.

* Fix virtualization of RDPID

* Virtualization of DR6_BUS_LOCK, which on bare metal is new in
  the 5.13 merge window

* More nested virtualization migration fixes (nSVM and eVMCS)

* Fix for KVM guest hibernation

* Fix for warning in SEV-ES SRCU usage

* Block KVM from loading on AMD machines with 5-level page tables,
  due to the APM not mentioning how host CR4.LA57 exactly impacts
  the guest.
