Since p_flag is often manipulated in interrupts and without biglock
it's a good idea to use atomic.h operations on it. This mechanic change updates all bit operations on p_flag to atomic_{set,clear}bits_int. Only exception is that P_OWEUPC is set by MI code before calling need_proftick and it's automatically cleared by ADDUPC. There's no reason for MD handling of that flag since everyone handles it the same way. kettenis@ ok
