We have to turn off the "polling nrflag" bit when we sleep the cpu like this, so that we'll get a cross-cpu interrupt to wake the processor up from the yield. We also have to disable PSTATE_IE in %pstate around the yield call and recheck need_resched() in order to avoid any races. Signed-off-by: David S. Miller <davem@davemloft.net>
