This commit prepares ARM by adding the call to enable_sched_clock_irqtime() in sched_clock(). We introduce a new kernel parameter - irqtime - which takes an integer. -1 for auto, 0 for disabled, and 1 for enabled. Auto mode selects IRQ accounting if we have a sched_clock() tick rate greater than 1MHz. Frederic Weisbecker is working on a patch set which moves the IRQ_TIME_ACCOUNTING into arch/, so that part is not incorporated into this patch; this facility becomes available on ARM only when both this patch and Frederic's patches are merged.
