No other (polling) idle functions can be used, therefore TIF_POLLING_NRFLAG is unnecessary, so lets remove it. Peter Zijlstra said: > Most archs have (x86) hlt or (arm) wfi like idle instructions, and if > that is your only possible idle function, you'll require the interrupt > to wake up and there's really no point to having the POLLING bit.
