2012-11-23dm: fix deadlock with request based dm and queue request_fn recursionJens Axboe1-1/+7
Request based dm attempts to re-run the request queue off the request completion path. If used with a driver that potentially does end_io from its request_fn, we could deadlock trying to recurse back into request dispatch. Fix this by punting the request queue run to kblockd. Tested to fix a quickly reproducible deadlock in such a scenario. Cc: [email protected] Acked-by: Alasdair G Kergon <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2012-11-23floppy: destroy floppy workqueue before cleaning up the queueJiri Kosina1-2/+3
We need to first destroy the floppy_wq workqueue before cleaning up the queue. Otherwise we might race with still pending work with the workqueue, but all the block queue already gone.

2012-11-23ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and aboveDave Martin1-1/+13
Modern GCC can generate code which makes use of the CPU's native unaligned memory access capabilities. This is useful for the C decompressor implementations used for unpacking compressed kernels. This patch disables alignment faults and enables the v6 unaligned access model on CPUs which support these features (i.e., v6 and later), allowing full unaligned access support for C code in the decompressor. The decompressor C code must not be built to assume that unaligned access works if support for v5 or older platforms is included in the kernel. For correct code generation, C decompressor code must always use the get_unaligned and put_unaligned accessors when dealing with unaligned pointers, regardless of this patch.

2012-11-22ipv4: do not cache looped multicastsJulian Anastasov1-2/+5
Starting from 3.6 we cache output routes for multicasts only when using route to 224/4. For local receivers we can set RTCF_LOCAL flag depending on the membership but in such case we use maddr and saddr which are not caching keys as before. Additionally, we can not use same place to cache routes that differ in RTCF_LOCAL flag value. Fix it by caching only RTCF_MULTICAST entries without RTCF_LOCAL (send-only, no loopback). As a side effect, we avoid unneeded lookup for fnhe when not caching because multicasts are not redirected and they do not learn PMTU. Thanks to Maxime Bizon for showing the caching problems in __mkroute_output for 3.6 kernels: different RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or ip_output call and the visible problem is that traffic can not reach local receivers via loopback.

2012-11-22[media] mt9v022: fix the V4L2_CID_EXPOSURE controlAnatolij Gustschin1-3/+8
Since the MT9V022_TOTAL_SHUTTER_WIDTH register is controlled in manual mode by V4L2_CID_EXPOSURE control, it shouldn't be written directly in mt9v022_s_crop(). In manual mode this register should be set to the V4L2_CID_EXPOSURE control value. Changing this register directly and outside of the actual control function means that the register value is not in sync with the corresponding control value. Thus, the following problem is observed: - setting this control initially succeeds - VIDIOC_S_CROP ioctl() overwrites the MT9V022_TOTAL_SHUTTER_WIDTH register - setting this control to the same value again doesn't result in setting the register since the control value was previously cached and doesn't differ Remove MT9V022_TOTAL_SHUTTER_WIDTH register setting in mt9v022_s_crop() and add a comment explaining why it is not needed in manual mode.

2012-11-22md/raid10: decrement correct pending counter when writing to replacement.NeilBrown1-1/+1
When a write to a replacement device completes, we carefully and correctly found the rdev that the write actually went to and the blithely called rdev_dec_pending on the primary rdev, even if this write was to the replacement. This means that any writes to an array while a replacement was ongoing would cause the nr_pending count for the primary device to go negative, so it could never be removed. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid10: close race that lose writes lost when replacement completes.NeilBrown1-61/+68
When a replacement operation completes there is a small window when the original device is marked 'faulty' and the replacement still looks like a replacement. The faulty should be removed and the replacement moved in place very quickly, bit it isn't instant. So the code write out to the array must handle the possibility that the only working device for some slot in the replacement - but it doesn't. If the primary device is faulty it just gives up. This can lead to corruption. So make the code more robust: if either the primary or the replacement is present and working, write to them. Only when neither are present do we give up. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-21fix incorrect NR_FREE_PAGES accounting (appears like memory leak)Dave Hansen1-1/+1
There have been some 3.7-rc reports of vm issues, including some kswapd bugs and, more importantly, some memory "leaks": http://www.spinics.net/lists/linux-mm/msg46187.html https://bugzilla.kernel.org/show_bug.cgi?id=50181 Commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page immediately when it is made available") took split_free_page() and reused it for the compaction code. It does something curious with capture_free_page() (previously known as split_free_page()): int capture_free_page(struct page *page, int alloc_order, ... __mod_zone_page_state(zone, NR_FREE_PAGES, -(1UL << order)); - /* Split into individual pages */ - set_page_refcounted(page); - split_page(page, order); + if (alloc_order != order) + expand(zone, page, alloc_order, order, + &zone->free_area[order], migratetype); Note that expand() puts the pages _back_ in the allocator, but it does not bump NR_FREE_PAGES. We "return" 'alloc_order' worth of pages, but we accounted for removing 'order' in the __mod_zone_page_state() call. For the old split_page()-style use (order==alloc_order) the bug will not trigger. But, when called from the compaction code where we occasionally get a larger page out of the buddy allocator than we need, we will run in to this. This patch simply changes the NR_FREE_PAGES manipulation to the correct 'alloc_order' instead of 'order'. I've been able to repeatedly trigger this in my testing environment. The amount "leaked" very closely tracks the imbalance I see in buddy pages vs. NR_FREE_PAGES. I have confirmed that this patch fixes the imbalance Signed-off-by: Dave Hansen <[email protected]> Acked-by: Mel Gorman <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2012-11-22md/raid5: Make sure we clear R5_Discard when discard is finished.NeilBrown1-2/+5
commit 9e44476851e91c86c98eb92b9bc27fb801f89072 MD: raid5 avoid unnecessary zero page for trim change raid5 to clear R5_Discard when the complete request is handled rather than when submitting the per-device discard request. However it did not clear R5_Discard for the parity device. This means that if the stripe_head was reused before it expired from the cache, the setting would be wrong and a hang would result. Also if the R5_Uptodate bit happens to be set, R5_Discard again won't be cleared. But R5_Uptodate really should be clear at this point. So make sure R5_Discard is cleared in all cases, and clear R5_Uptodate when a 'discard' completes. Signed-off-by: NeilBrown <[email protected]>
2012-11-22md/raid5: move resolving of reconstruct_state earlier inNeilBrown1-34/+34
stripe_handle. The chunk of code in stripe_handle which responds to a *_result value in reconstruct_state is really the completion of some processing that happened outside of handle_stripe (possibly asynchronously) and so should be one of the first things done in handle_stripe(). After the next patch it will be important that it happens before handle_stripe_clean_event(), as that will clear some dev->flags bit that this code tests. Signed-off-by: NeilBrown <[email protected]>

2012-11-21ARM - OMAP: ads7846: fix pendown debounce settingIgor Grinberg1-14/+20
Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the pendown GPIO debounce time setting by the below sequence: gpio_request_one() gpio_set_debounce() gpio_free() It also revealed a bug in the OMAP GPIO handling code which prevented the GPIO debounce clock to be disabled and CORE transition to low power states. Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on free/reset) fixes the OMAP GPIO handling code by making sure that the GPIO debounce clock gets disabled if no GPIO is requested from current bank. While fixing the OMAP GPIO handling code (in the right way), the above commit makes the gpio_request->set_debounce->free sequence invalid as after freeing the GPIO, the debounce settings are lost. Fix the debounce settings by moving the debounce initialization to the actual GPIO requesting code - the ads7846 driver.

2012-11-21Input: ads7846 - enable pendown GPIO debounce time settingIgor Grinberg2-3/+8
Some platforms need the pendown GPIO debounce time setting programmed. Since the pendown GPIO is handled by the driver, the debounce time should also be handled along with the pendown GPIO request. Signed-off-by: Igor Grinberg <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
2012-11-21[media] adv7604: restart STDI once if format is not foundHans Verkuil1-0/+24
The STDI block may measure wrong values, especially for lcvs and lcf. If the driver can not find any valid timing, the STDI block is restarted to measure the video timings again. The function will return an error, but the restart of STDI will generate a new STDI interrupt and the format detection process will restart.

Use predefined video timings (prim_mode/vid_std) when available as recommended by Analog Devices (http://ez.analog.com/message/48267#48267). Also remove 720p30 support since the ADV7604 can't handle that.

2012-11-21[media] adv7604: Replace prim_mode by modeHans Verkuil2-60/+39
Changes the way the primary mode is handled: - Remove it from platform_data since it doesn't belong there. - Add a new mode enum for use with s_routing. - Collapse the two HDMI modes into one HDMI mode: when setting up the timings manually we do not need to select HDMI_COMP mode. That's only needed when selecting a preset. This patch prepares for the next step where we switch to using the presets where available.

2012-11-21team: bcast: convert return value of team_dev_queue_xmit() to bool correctlyJiri Pirko1-3/+3
The thing is that team_dev_queue_xmit() returns NET_XMIT_* or -E*. bc_trasmit() should return true in case all went well. So use ! to get correct retval from team_dev_queue_xmit() result. This bug caused iface statistics to be badly computed.
