Code intended to check DMA status was checking DMA command register. Moreover firmware seems to "forget" to set DMA capable bit for the slave device (at least in RAID mode but without ITE RAID volumes) so check device ID for DMA capable bit when deciding whether to use DMA and remove DMA status check completely. Thanks to Pavol Simo for the bugreport and testing the initial fix. This change unfortunately still doesn't fix DMA in RAID mode (which works fine with IDE it821x) but Alan is working on the missing pieces (pata_it821x vs libata EH issues).

- Disable CLFLUSH again; it is still broken. Always do WBINVD. - Always flush in the i386 case, not only when there are deferred pages. These are both brute-force inefficient fixes, to be improved next release cycle. The changes to i386 are a little more extensive than strictly needed (some dead code added), but it is more similar to the x86-64 version now and the dead code will be used soon.

The "is_exec" branch of the protection check in do_page_fault() didn't do anything on 32-bit PowerPC. So if a userland program jumps to a page with Linux protection flags "---p", all the tests happily fall through, and handle_mm_fault() is called, which in turn calls handle_pte_fault(), which calls update_mmu_cache(), which goes flush the dcache to a page with no access rights.

The old snd-powermac driver has some serious refcounting issues when initialisation fails, which is the case on all new machines with a layout-id since those are handled by the new snd-aoa driver. Some of those bugs seem to have been under the radar for some time (like double pci_dev_put), but one was actually added in 2.6.22 with Stephen attempt at teaching refcounting to the driver which didn't do it at all. This patch fixes both, thus removing all sort of kref errors that would happen if that driver gets loaded on a G5 machine or a recent PowerBook due to OF nodes left around with a 0 refcount.

Miklos Szeredi reported very long pauses (several seconds, sometimes more) on his T60 (with a Core2Duo) which he managed to track down to wait_task_inactive()'s open-coded busy-loop. He observed that an interrupt on one core tries to acquire the runqueue-lock but does not succeed in doing so for a very long time - while wait_task_inactive() on the other core loops waiting for the first core to deschedule a task (which it wont do while spinning in an interrupt handler). This rewrites wait_task_inactive() to do all its waiting optimistically without any locks taken at all, and then just double-check the end result with the proper runqueue lock held over just a very short section. If there were races in the optimistic wait, of a preemption event scheduled the process away, we simply re-synchronize, and start over. So the code now looks like this: repeat: /* Unlocked, optimistic looping! */ rq = task_rq(p); while (task_running(rq, p)) cpu_relax(); /* Get the *real* values */ rq = task_rq_lock(p, &flags); running = task_running(rq, p); array = p->array; task_rq_unlock(rq, &flags); /* Check them.. */ if (unlikely(running)) { cpu_relax(); goto repeat; } /* Preempted away? Yield if so.. */ if (unlikely(array)) { yield(); goto repeat; } Basically, that first "while()" loop is done entirely without any locking at all (and doesn't check for the case where the target process might have been preempted away), and so it's possibly "incorrect", but we don't really care. Both the runqueue used, and the "task_running()" check might be the wrong tests, but they won't oops - they just mean that we could possibly get the wrong results due to lack of locking and exit the loop early in the case of a race condition. So once we've exited the loop, we then get the proper (and careful) rq lock, and check the running/runnable state _safely_. And if it turns out that our quick-and-dirty and unsafe loop was wrong after all, we just go back and try it all again. (The patch also adds a lot of comments, which is the actual bulk of it all, to make it more obvious why we can do these things without holding the locks). Thanks to Miklos for all the testing and tracking it down.

Gene Heskett reported the following problem while testing CFS: SysRq-N is not always effective in normalizing tasks back to SCHED_OTHER. The reason for that turns out to be the following bug: - normalize_rt_tasks() uses for_each_process() to iterate through all tasks in the system. The problem is, this method does not iterate through all tasks, it iterates through all thread groups. The proper mechanism to enumerate over all threads is to use a do_each_thread() + while_each_thread() loop.
