Err find_first_bit ?

I guess that will work but your hand-coded version is so much faster :)

I would need to abstract sched_find_first_bit into a generic function
that also accepted a size argument.  Something like:

Rename sched_find_first_bit to _sched_find_first_bit, and

#if MAX_RT_PRIO < 120 && MAX_RT_PRIO > 99
#define sched_find_first_bit(b, size)	_sched_find_first_bit(b)
#else
#define sched_find_first_bit(b, size)	find_first_bit(b, size)
#endif

We can let MAX_RT_PRIO go up 120 since the bitmap is actually 160, not
140, size 5*32=160.

Look good?
