KVM: s390: Features and Test for 5.11
- memcg accouting for s390 specific parts of kvm and gmap
- selftest for diag318
- new kvm_stat for when async_pf falls back to sync
The selftest even triggers a non-critical bug that is unrelated
to diag318, fix will follow later.
KVM: s390: track synchronous pfault events in kvm_stat
Right now we do count pfault (pseudo page faults aka async page faults
start and completion events). What we do not count is, if an async page
fault would have been possible by the host, but it was disabled by the
guest (e.g. interrupts off, pfault disabled, secure execution....). Let
us count those as well in the pfault_sync counter.
