Why don't we hold off on Wanpeng's patch and instead apply the one I proposed
to call check_nested_events() when checking for interrupt in inject_pending_event() ?

I think that will take care of https://bugzilla.kernel.org/show_bug.cgi?id=72381 
too. Once, we figure out what's causing hangs under certain conditions with his 
patch, we can apply that and revert this change.
