The Meta idle function jumps into the interrupt handler which efficiently blocks waiting for the next interrupt when it reads the interrupt status register (TXSTATI). 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.
