I'd prefer to inline
cpu_is_idle(), but optimizing the idle code path is probably not that important ;-)Sure it is, in one way: how fast can you get back to work? (not OK to take a millisecond getting out of the idle loop)
2 short function calls instead of 2 "if(current->need_resched)" on the way out.
I didn't try very hard to fix the inline dependencies, could you try to move cpu_is_idle() from kernel/sched.c into <linux/pm.h>?
I'm sure it won't be more difficult than the last "Athlon+SMP doesn't compile" problem ;-)
