[PATCH 0/2] KVM: x86: Convey the exit reason to user-space on emulation failure

[David Edmondson]

To aid in debugging failures in the field, when instruction emulation
fails, report the VM exit reason to userspace in order that it can be
recorded.

The changes are on top of Aaron's patches from
https://lore.kernel.org/r/20210510144834.658457-1-aaronlewis@xxxxxxxxxx
which are in the KVM queue, but not yet upstream.
