    Pass mode to wait_on_atomic_t() action funcs and provide default actions · 5e4def20
    David Howells authored
    Make wait_on_atomic_t() pass the TASK_* mode onto its action function as an
    extra argument and make it 'unsigned int throughout.
    
    Also, consolidate a bunch of identical action functions into a default
    function that can do the appropriate thing for the mode.
    
    Also, change the argument name in the bit_wait*() function declarations to
    reflect the fact that it's the mode and not the bit number.
    
    [Peter Z gives this a grudging ACK, but thinks that the whole atomic_t wait
    should be done differently, though he's not immediately sure as to how]
