After commit 07721feee46b ("KVM: nVMX: Don't emulate instructions in guest mode") Hyper-V guests on KVM stopped booting and tracing shows that we're trying to emulate an instruction which shouldn't be intercepted. Turns out, x86_emulate_ctxt may hold a stale 'intercept' value.
This is a regression in 5.6-rc4 and I'm marking PATCH1 for stable@. The commit 07721feee46b ("KVM: nVMX: Don't emulate instructions in guest mode") is, however, correct, it just seems to reveal a pre-existing condition.
