mv78xx0 and kirkwood use identical mpp code. It should also be possible to rewrite the orion5x mpp to use this platform code. Signed-off-by:

The core interrupt chip is a straight forward conversion. The gpio chip is implemented with two instances of the irq_chip_type which can be switched with the irq_set_type function. That allows us to use the generic callbacks and avoids the conditionals in them. Signed-off-by:

These callbacks are only called in the syscore suspend/resume code on interrupt chips which have been registered via the generic irq chip mechanism. Calling those callbacks per irq would be rather icky, but with the generic irq chip mechanism we can call this per registered chip. Signed-off-by:

Paul Mundt authored
This adds support for disabling threading on a per-IRQ basis via the IRQ status instead of the IRQ flow, which is necessary for interrupts that don't follow the natural IRQ flow channels, such as those that are virtually created. The new APIs added are simply: irq_set_thread() irq_set_nothread() which follow the rest of the IRQ status routines. Chained handlers also have IRQ_NOTHREAD set on them automatically, making the lack of threading explicit rather than implicit. Subsequently, the nothread flag can be viewed through the standard genirq debugging facilities. [ tglx: Fixed cleanup fallout ] Signed-off-by:

Rather than pass in some random truncated offset to the pid-related functions, check that the offset is in range up-front. This is just cleanup, the previous commit fixed the real problem. Cc: stable@kernel.org Signed-off-by:

next_pidmap() just quietly accepted whatever 'last' pid that was passed in, which is not all that safe when one of the users is /proc. Admittedly the proc code should do some sanity checking on the range (and that will be the next commit), but that doesn't mean that the helper functions should just do that pidmap pointer arithmetic without checking the range of its arguments. So clamp 'last' to PID_MAX_LIMIT. The fact that we then do "last+1" doesn't really matter, the for-loop does check against the end of the pidmap array properly (it's only the actual pointer arithmetic overflow case we need to worry about, and going one bit beyond isn't going to overflow). [ Use PID_MAX_LIMIT rather than pid_max as per Eric Biederman ] Reported-by:

Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254a ("Input: xen-kbdfront - advertise either absolute or relative coordinates"). Driver on restore should ask xen for request-abs-pointer again if it is available. So restore parts that did it before 5ea5254a. Acked-by:

The free space caching code was recently reworked to cache all the pages it needed instead of using find_get_page everywhere. One loop was missed though, so it ended up leaking pages. This fixes it to use our page array instead of find_get_page. Signed-off-by:

Instead of overloading __blk_run_queue to force an offload to kblockd add a new blk_run_queue_async helper to do it explicitly. I've kept the blk_queue_stopped check for now, but I suspect it's not needed as the check we do when the workqueue items runs should be enough. Signed-off-by:

We just need to make sure that an unplug event wakes up the md thread, which is exactly what mddev_check_plugged does. Also remove some plug-related code that is no longer needed. Signed-off-by:

In raid5 plugging is used for 2 things: 1/ collecting writes that require a bitmap update 2/ collecting writes in the hope that we can create full stripes - or at least more-full. We now release these different sets of stripes when plug_cnt is zero. Also in make_request, we call mddev_check_plug to hopefully increase plug_cnt, and wake up the thread at the end if plugging wasn't achieved for some reason. Signed-off-by:

When an md device adds a request to a queue, it can call mddev_check_plugged. If this succeeds then we know that the md thread will be woken up shortly, and ->plug_cnt will be non-zero until then, so some processing can be delayed. If it fails, then no unplug callback is expected and the make_request function needs to do whatever is required to make the request happen. Signed-off-by:

md has some plugging infrastructure for RAID5 to use because the normal plugging infrastructure required a 'request_queue', and when called from dm, RAID5 doesn't have one of those available. This relied on the ->unplug_fn callback which doesn't exist any more. So remove all of that code, both in md and raid5. Subsequent patches with restore the plugging functionality. Signed-off-by:

If we know we are going to punt to kblockd, we can drop the queue lock before calling into __blk_run_queue() since it only does a safe bit test and a workqueue call. Since kblockd needs to grab this very lock as one of the first things it does, it's a good optimization to drop the lock before waking kblockd. Signed-off-by:
