Presently only the first 2 counters are supported, as these are the ones of the most interest to the perf tool and end users. Counter chaining is not presently handled, so these are simply implemented as 32-bit counters. This also establishes a perf event support framework for other hardware counters, which the existing SH-4 oprofile code will migrate over to as the SH-4A support evolves.

Unfortunately due to ll/sc semantics an explicit synco is needed in these cases, which is sorted for us by just switching these over to smp_mb(). smp_mb() also has the benefit of being wrapped to barrier() in the UP and non-SH4A cases, so old behaviour is maintained for those parts.

Previously this was forcing secondary CPUs in to sleep mode with them not coming back if they didn't have their own local timers. Given that we use clockevents broadcasting by default, the CPU managing the clockevents can't have IRQs disabled before entering its sleep state. This unfortunately leaves us with the age-old need_resched() race in between local_irq_enable() and cpu_sleep(), but at present this is unavoidable. After some more experimentation it may be possible to layer on SR.BL bit manipulation over top of this scheme to inhibit the race condition, but given the current potential for missing wakeups, this is left as a future exercise.

This resulted in inconsistent sleep modes depending on which CPU we were on, confusing the idle loop when not polling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
