Hi folks,
what's the status of the SGI support for the IA64 SN2-specific
altic mmtimer (drivers/char/mmtimer.c)? It's the only driver that
register a k_lock outside the core kernel, so if we could get rid of
it because the remaining IA64 user are all on somewhat old distros
anyway it would make our life a whole lot easier.

Since this is SN2 specific, this can be removed.

Note that the mmtimer struct can probably be removed from the k_itimer struct
in include/linux/posix-timers.h, just for completeness.
