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 ;-) -- Manfred - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
