[PATCH] reduce number of parameters to __wait_on_bit() and __wait_on_bit_lock()
Some of the parameters to __wait_on_bit() and __wait_on_bit_lock() are
redundant, as the wait_bit_queue parameter holds the flags word and the bit
number. This patch updates __wait_on_bit() and __wait_on_bit_lock() to
fetch that information from the wait_bit_queue passed to them and so reduce
the number of parameters so that -mregparm may be more effective.
Incremental atop the complete out-of-lining of the contention cases and the
fastcall and wait_on_bit_lock()/test_and_set_bit() fixes.
