Pass mode to wait_on_atomic_t() action funcs and provide default actions
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] Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Peter Zijlstra <peterz@infradead.org> cc: Ingo Molnar <mingo@kernel.org>
