| |
Treat #PFs that occur during emulation of ENCLS as, wait for it, emulated page faults. Practically speaking, this is a glorified nop as the exception is never of the nested flavor, and it's extremely unlikely the guest is relying on the side effect of an implicit INVLPG on the faulting address.
