    -ENOMEM.

Hm. What I did simply mimics this ("arch/arm/include/asm/localtimer.h"):

#ifdef CONFIG_LOCAL_TIMERS
[...]
#else

static inline int local_timer_setup(struct clock_event_device *evt)
{
        return -ENXIO;
}

Now, I had a look at "include/asm-generic/errno-base.h":

#define ENXIO            6      /* No such device or address */
[...]
#define ENOMEM          12      /* Out of memory */

and to be honest, ENXIO makes more sense to me, but I really have no
strong feelings either way... Do you?

Thanks for your time!

Pawe?
