Improve and bugfix CRIS v10 fast timers. - irq_handler_t now only takes two arguments. - Keep interrupts disabled as long as we have a reference to the fasttimer list and only enable them while doing the callback. del_fast_timer may be called from other interrupt context. - Fix bug where debug code could return without calling local_irq_restore. - Use jiffies instead of usec (change from struct timeval to fasttime_t). - Don't initialize static variables to zero. - Remove obsolete #ifndef DECLARE_WAITQUEUE code. - fast_timer_init should be __initcall. - Change status/debug variables to unsigned. - Remove CVS log and CVS id.
