* xtime_lock vs update_process_timesPeter Zijlstra2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d3d74453c34f8fd87674a8cf5b8a327c68f22e99 ("hrtimer: fixup the HRTIMER_CB_IRQSAFE_NO_SOFTIRQ fallback") broke several archs, and since only Russell bothered to merge the fix, and Greg to ACK his arch, I'm sending this for merger. I have confirmation that the Alpha bit results in a booting kernel. That leaves: blackfin, frv, sh and sparc untested. The deadlock in question was found by Russell: IRQ handle -> timer_tick() - xtime seqlock held for write -> update_process_times() -> run_local_timers() -> hrtimer_run_queues() -> hrtimer_get_softirq_time() - tries to get a read lock Now, Thomas assures me the fix is trivial, only do_timer() needs to be done under the xtime_lock, and update_process_times() can savely be removed from under it.

* sh: Add SH7263 CPU support.Paul Mundt2008-01-27
| | | | | | | | | | | | This adds support for the SH7263 (SH-2A) CPU. This particular CPU is a superset of SH7203, adding some additional peripheral blocks and hooking up additional (reserved on SH7203) vectors in the INTC block. No visibly nasty surprises, yet..

* sh: Clock framework tidying.Paul Mundt2006-12-05
| | | | | | | | This syncs up the SH clock framework with the linux/clk.h API, for which there were only some minor changes required, namely the clk_get() dev_id and subsequent callsites. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Turn off IRQs around get_timer_offset() calls.Paul Mundt2006-12-05
| | | | | | | | | Since all of the sys_timer sources currently do this on their own within the ->get_offset() path, it's more sensible to just have the caller take care of it when grabbing xtime_lock. Incidentally, this is more in line with what others (ie, ARM) are doing already. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Configurable timer IRQ.Paul Mundt2006-12-05
| | | | | | | | | All of the various CPU subtypes currently hardcode TIMER_IRQ, switch this to a config option in the few places we need this. This allows further removal of hardcoded IRQ headers.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
