To allow better diagnosis of tick-sched related, especially NOHZ related problems, we need to know when the last wakeup via an irq happened and when the CPU left the idle state. Add two fields (idle_waketime, idle_exittime) to the tick_sched structure and add them to the timer_list output. Signed-off-by:

xtime_cache needs to be updated whenever xtime and or wall_to_monotic are changed. Otherwise users of xtime_cache might see a stale (and in the case of timezone changes utterly wrong) value until the next update happens. Fixup the obvious places, which miss this update. Signed-off-by:

this patch: commit 37bb6cb4 Author: Peter Zijlstra <a.p.zijlstra@chello.nl> Date: Fri Jan 25 21:08:32 2008 +0100 hrtimer: unlock hrtimer_wakeup Broke hrtimer_init_sleeper() users. It forgot to fix up the futex caller of this function to detect the failed queueing and messed up the do_nanosleep() caller in that it could leak a TASK_INTERRUPTIBLE state. Signed-off-by:

It blindly copies everything in the io_context, including the lock. That doesn't work so well for either lock ordering or lockdep. There seems zero point in swapping io contexts on a request to request merge, so the best point of action is to just remove it. Signed-off-by:Jens Axboe <jens.axboe@oracle.com>

Modify Makefiles to support separate coldfire platform directory. Currently the common ColdFire CPU family code sits in the arch/m68knommu/platform/5307 directory. This is confusing, the files containing this common code are in no way specific to the 5307 ColdFire. Create an arch/m68knommu/platform/coldfire directory to contain this common code. Other m68knommu CPU varients do not need use this code though, so it doesn't make sense to move it to arch/m68knommu/kernel. Signed-off-by:
