  KVM: selftests: smm_test: Test SMM enter from L2 (2021-07-15 10:19:44 -0400)

----------------------------------------------------------------
* Allow again loading KVM on 32-bit non-PAE builds

* Fixes for host SMIs on AMD

* Fixes for guest SMIs on AMD

* Fixes for selftests on s390 and ARM

* Fix memory leak

* Enforce no-instrumentation area on vmentry when hardware
  breakpoints are in use.
