--------------------------------

commit f4b027c5 upstream.

Override the Processor Trace (PT) interrupt handler for guest mode if and
only if PT is configured for host+guest mode, i.e. is being used
independently by both host and guest.  If PT is configured for system
mode, the host fully controls PT and must handle all events.

Fixes: 8479e04e ("KVM: x86: Inject PMI for KVM guest")
