From d8e5219f9f5ca7518eb820db9f3d287a1d46fcf5 Mon Sep 17 00:00:00 2001 From: Jesper Nilsson Date: Wed, 14 Nov 2007 17:01:23 -0800 Subject: CRISv10 improve and bugfix fasttimer 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.
