This kept the code simple enough but is now causing issues with kexec." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MPI: Fix compilation on MIPS with GCC 4.4 and newer MIPS: Fix crash that occurs when function tracing is enabled MIPS: Merge overlapping bootmem ranges 26 November 2012, 01:55:04 UTC
e716e01 Gavin Shan 22 November 2012, 21:58:26 UTC powerpc/eeh: Do not invalidate PE properly While the EEH does recovery on the specific PE that has PCI errors, the PCI devices belonging to the PE will be removed and the PE will be marked as invalid since we still need the information stored in the PE. We only invalidate the PE when it doesn't have associated EEH devices and valid child PEs. However, the code used to check that is wrong. The patch fixes that.

The initial fix wasn't quite complete, so it's in two parts. In fact the first part is committed twice (Artem committed his own copy of the same patch) and I've merged Artem's tree into mine which already had that fix. I'd have recommitted that to make it somewhat cleaner, but figured by this point in the release cycle it was better to merge *exactly* the commits which have been in linux-next. If I'd recommitted, I'd also omit the sparse warning fix. But it's there, and it's harmless — just marking one function as 'static' in onenand code. This also includes a couple more fixes for stable: an AB-BA deadlock in JFFS2, and an invalid range check in slram." * tag 'for-linus-20121123' of git://git.infradead.org/mtd-2.6: mtd: nand: fix Samsung SLC detection regression mtd: nand: fix Samsung SLC NAND identification regression jffs2: Fix lock acquisition order bug in jffs2_write_begin mtd: onenand: Make flexonenand_set_boundary static mtd: slram: invalid checking of absolute end address mtd: ofpart: Fix incorrect NULL check in parse_ofoldpart_partitions() mtd: nand: fix Samsung SLC NAND identification regression 24 November 2012, 01:12:17 UTC

0e622d3 Andreas Larsson 23 November 2012, 11:24:09 UTC of/address: sparc: Declare of_iomap as an extern function for sparc again This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.

Checking just for non-zero return code leads to erroneous setting of the req->dev pointer to NULL, which then leads to a repeated call to dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler().

893d290 Roland Dreier 22 November 2012, 10:00:11 UTC block: Don't access request after it might be freed After we've done __elv_add_request() and __blk_run_queue() in blk_execute_rq_nowait(), the request might finish and be freed immediately. Therefore checking if the type is REQ_TYPE_PM_RESUME isn't safe afterwards, because if it isn't, rq might be gone. Instead, check beforehand and stash the result in a temporary. This fixes crashes in blk_execute_rq_nowait() I get occasionally when running with lots of memory debugging options enabled -- I think this race is usually harmless because the window for rq to be reallocated is so small.

6361742 Julian Anastasov 22 November 2012, 21:04:14 UTC ipv4: do not cache looped multicasts 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.

884162d NeilBrown 22 November 2012, 04:12:09 UTC md/raid10: decrement correct pending counter when writing to replacement. 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.

e7c0c3f NeilBrown 22 November 2012, 03:42:49 UTC md/raid10: close race that lose writes lost when replacement completes. 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.

ef6c5be Dave Hansen 21 November 2012, 19:21:51 UTC fix incorrect NR_FREE_PAGES accounting (appears like memory leak) 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.

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.

0a0d628 Igor Grinberg 21 November 2012, 07:00:51 UTC ARM - OMAP: ads7846: fix pendown debounce setting 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.

Regarding the mac80211 tree, Johannes says: "Please pull my mac80211.git tree (see below) to get two more fixes for 3.7. Both fix regressions introduced *before* this cycle that weren't noticed until now, one for IBSS not cleaning up properly and the other to add back the "wireless" sysfs directory for Fedora's startup scripts." Regarding the iwlwifi tree, Johannes says: "Please also pull my iwlwifi.git tree, I have two fixes: one to remove a spurious warning that can actually trigger in legitimate situations, and the other to fix a regression from when monitor mode was changed to use the "sniffer" firmware mode." Also included is an nfc tree pull. Samuel says: "We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix. Moreover, we also have an LLCP adapter linked list insertion fix." On top of that, a few more bits... Albert Pool adds a USB ID to rtlwifi. Bing Zhao provides two mwifiex fixes -- one to fix a system hang during a command timeout, and the other to properly report a suspend error to the MMC core.

It broke xentrace as it used xc_map_foreign() instead of xc_map_foreign_bulk(). Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious that it broke. The return value is set early on to -EINVAL, and if all goes well, the "set top bits of the MFN's" never gets called, so the return value is still EINVAL when the function gets to the end, causing the caller to think it went wrong (which it didn't!)

982b604 Russell King 20 November 2012, 12:18:52 UTC ASoC: kirkwood-i2s: fix DMA underruns Stress testing the driver with multiple start/stop events causes kirkwood-dma to report underrun errors (which used to cause the kernel to lock up solidly). This is because kirkwood-i2s is not respecting the restrictions imposed on clearing the 'pause' bit. Follow what the spec says; the busy bit must be read as being clear twice before the pause bit can be released. This solves the underruns. However, it has been noticed that the busy bit occasionally does not clear itself, hence the waiting is bounded to 5ms maximum to avoid a new reason for the kernel to lockup.

2424d45 Russell King 20 November 2012, 12:18:32 UTC ASoC: kirkwood-i2s: fix DCO lock detection This is part of a patch found in Rabeeh Khoury's git tree for the cubox, which is further attributed to Sebastian Hesselbrath. Rather than masking the KIRKWOOD_DCO_SPCR_STATUS register contents against the registers virtual address, let's actually use the bit definition for the locked status, as required in the documentation.

25ec6bb Russell King 20 November 2012, 12:18:11 UTC ASoC: kirkwood-dma: don't ignore other irq causes on error Ignoring the real cause of the interrupt is not a good idea; this behaviour has been observed to bring Dove platforms to silently lockup. Instead, on error fall through to the normal interrupt processing. This is especially important on Dove platforms as errors are handled separately, and allows us to clear down the real cause of the interrupt.

ae6a5d3 Russell King 20 November 2012, 12:17:51 UTC ASoC: kirkwood-dma: fix use of virt_to_phys() This is part of a patch found in Rabeeh Khoury's git tree for the cubox. You can not use virt_to_phys() on the address returned from dma_alloc_coherent(); it may not be part of the kernel direct-mapped memory. Fix this to use the DMA address instead.

So, follow the example of misc.c and #undef memcpy so that we use the version provided by misc.c.
