I'm just mimicking __context_tracking_enter and vs.
context_tracking_enter. So it is at least consistent with those functions.
The guest ones are not quite as consistent. I can fix that later,
there's no reason also to have guest context tracking split between
include/linux/context_tracking.h and include/linux/kvm_host.h.
Thanks,
