* Check that nEPT/nNPT is enabled in slow flush hypercalls. If it is
not, the hypercalls can be processed as usual even while running a
nested guest.
* Fix shadow paging use-after-free due to page tables changing outside
execution of the guest. A bug that is 16 years old and stems from an
imprecision in the very first KVM series.
* Scan IRR whenever PID.ON is true, even if PIR is empty, which avoids
a somewhat rare WARN.

not, the hypercalls can be processed as usual even while running a
nested guest
- Fix shadow paging use-after-free due to page tables changing
