Hypervisor Virtualization and Directed Hypervisor Doorbell interrupt
handlers use the macro EXC_VIRT_OOL_MASKABLE_HV for their relocation-on
handlers, which calls MASKABLE_RELON_EXCEPTION_HV_OOL, which uses the
real mode interrupt prolog.
Use the RELON variant instead to reduce overhead.

paths")

I was hesitant about using the Fixes: tag on this one because it's not
a correctness bug as far as I can see.
Thanks,
Nick
