Yes please.  Though I think it probably makes sense to go with __vt_handle_notify()
to capture that it's an inner helper?  E.g. that's my plan for
__vt_handle_ept_violation().

Regardling handle_bus_lock_vmexit(), put it in main.c.  to_vt() currently lives
in vmx.h, which means it's impossible to inline vt_handle_bus_lock_vmexit() in
common.h because it can't get from "struct kvm_vcpu *vcpu" to "struct vcpu_vt *vt"
to update exit_reason.bus_lock_detected.

v2 of this series will address that (I coded everything up and tested it all last
week, just need to post it), but (a) juggling those dependencies isn't your
responsibility and (b) we don't want to take a dependency on the cleanups for a
fix that is destined for stable@.

Then I'll do one of three things: post a new version of this series to move
vt_handle_bus_lock_vmexit() to common.h, post a standalone patch to do the same,
or simply leave it in main.c (it's going to require a non-inline implementation
for at VMX since it's wired up to a function table, and it should be a rare path
so inlining for performance reasons is a non-goal).

Thanks!
