[PATCH 0/3] KVM: x86: Nested fixes (mostly #DF/#TF)

From: Sean Christopherson
Date: Wed Apr 06 2022 - 20:23:23 EST


Patch 1 removes an assertion that is going to fail miserably once KVM
allows save/restore of pending triple faults.

Patches 2 and 3 are fixes for edge cases for nVMX related to saving exit
info on failed VM-Entry, #DF and triple fault, that in all likelihood no
one cares about.

Sean Christopherson (3):
KVM: x86: Drop WARNs that assert a triple fault never "escapes" from
L2
KVM: nVMX: Leave most VM-Exit info fields unmodified on failed
VM-Entry
KVM: nVMX: Clear IDT vectoring on nested VM-Exit for double/triple
fault
