commit 9dd6f1c1 upstream. Due to a typo the illegal access interrupt is never cleared in by the interupt handler, causing an effective deadlock on the first illegal access. This was broken since the code was introduced in 5433acd8 ("MIPS: ralink: add illegal access driver"), but only exposed when the Kconfig symbol was added, thus enabling the code. Fixes: a7b7aad3 ("MIPS: ralink: add missing symbol for RALINK_ILL_ACC") Signed-off-by:

commit e058c945 upstream. According to the HSW b-spec we need to try clock divisors of 63 and 72, each 3 or more times, when attempting DP AUX channel communication on a server chipset. This actually wasn't happening due to a short-circuit that only checked the DP_AUX_CH_CTL_DONE bit in status rather than checking that the operation was done and that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set. [v2] Implemented alternate solution suggested by Jani Nikula. Signed-off-by:

In those cases, the cache levels and leaves will be zero and will result in following exception: Unable to handle kernel NULL pointer dereference at virtual address 0040 pgd = ffffffc0008fa000 [00000040] *pgd=00000009f6807003, *pud=00000009f6807003, *pmd=00000009f6808003, *pte=006000002c010707 Internal error: Oops: 96000005 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 1 Comm: swapper/0 Not tainted 4.1.0-rc5 #198 task: ffffffc9768a0000 ti: ffffffc9768a8000 task.ti: ffffffc9768a8000 PC is at detect_cache_attributes+0x98/0x2c8 LR is at detect_cache_attributes+0x88/0x2c8 kcalloc(0) returns a special value ZERO_SIZE_PTR which is non-NULL value but results in fault only on any attempt to dereferencing it.

commit 392bceed upstream. The driver configures the IDLE condition to interrupt the SDMA engine. Since the SDMA UART ROM script doesn't clear the IDLE bit itself, this caused repeated 1-byte DMA transfers, regardless of available data in the RX FIFO. Also, when returning due to the IDLE condition, the UART ROM script already increased its counter, causing residue to be off by one. This patch clears the IDLE condition to avoid repeated 1-byte DMA transfers and decreases count by when the DMA transfer was aborted due to the IDLE condition, fixing serial transfers using DMA on i.MX6Q.

commit a00918d0 upstream. Regression in commit 638139eb ("usb: hub: allow to process more usb hub events in parallel") The regression resulted in intermittent failure to initialise a 10-port hub (with three internal VL812 4-port hub controllers) on boot, with a failure rate of around 8%, due to multiple race conditions when accessing addr_dev and slot_id in struct xhci_hcd. This regression also exposed a problem with xhci_setup_device, which "should be protected by the usb_address0_mutex" but no longer is due to commit 6fecd4f2 ("USB: separate usb_address0 mutexes for each bus") With separate buses (and locks) it is no longer the case that a single lock will protect xhci_setup_device from accesses by two parallel threads processing events on the two buses. Fix this by adding a mutex to protect addr_dev and slot_id in struct xhci_hcd, and by making the assignment of slot_id atomic. Fixes multiple boot errors: [ 0.583008] xhci_hcd 0000:00:14.0: Bad Slot ID 2 [ 0.583009] xhci_hcd 0000:00:14.0: Could not allocate xHCI USB device data structures [ 0.583012] usb usb1-port3: couldn't allocate usb_device And: [ 0.637409] xhci_hcd 0000:00:14.0: Error while assigning device slot ID [ 0.637417] xhci_hcd 0000:00:14.0: Max number of devices this xHCI host supports is 32.

commit 9df56035 upstream. There are a few issues with the burst mode support. For one we don't setup the rx buffer, so the buffer will never be filled and all samples will read as the zero. Furthermore the tx buffer has the wrong type, which means the driver sends the wrong command and not the right data is returned. The final issue is that in burst mode all channels are transferred. Hence the length of the transfer length should be the number of hardware channels * 2 bytes. Currently the driver uses indio_dev->scan_bytes for this. But if the timestamp channel is enabled the scan_bytes will be larger than the burst length. Fix this by just calculating the burst length based on the number of hardware channels. Signed-off-by:

Joe Thornber authored
commit 1c220c69 upstream. dm_merge_bvec() was originally added in f6fccb ("dm: introduce merge_bvec_fn"). In that commit a value in sectors is converted to bytes using << 9, and then assigned to an int. This code made assumptions about the value of BIO_MAX_SECTORS. A later commit 148e51 ("dm: improve documentation and code clarity in dm_merge_bvec") was meant to have no functional change but it removed the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At this point the cast from sector_t to int resulted in a zero value. The fallout being dm_merge_bvec() would only allow a single page to be added to a bio. This interim fix is minimal for the benefit of stable@ because the more comprehensive cleanup of passing a sector_t to all DM targets' merge function will impact quite a few DM targets.

commit c0345ee5 upstream. The count variable is used to iterate down to (below) zero from the size of the bitmap and handle the one-filling the remainder of the last partial bitmap block. The loop conditional expects count to be signed in order to detect when the final block is processed, after which count goes negative. Unfortunately, a recent change made this unsigned along with some other related fields. The result of is this is that during mount, omfs_get_imap will overrun the bitmap array and corrupt memory unless number of blocks happens to be a multiple of 8 * blocksize. Fix by changing count back to signed: it is guaranteed to fit in an s32 without overflow due to an enforced limit on the number of blocks in the filesystem. Signed-off-by:

commit 6dfe5a04 upstream. xfs_attr_inactive() is supposed to clean up the attribute fork when the inode is being freed. While it removes attribute fork extents, it completely ignores attributes in local format, which means that there can still be active attributes on the inode after xfs_attr_inactive() has run. This leads to problems with concurrent inode writeback - the in-core inode attribute fork is removed without locking on the assumption that nothing will be attempting to access the attribute fork after a call to xfs_attr_inactive() because it isn't supposed to exist on disk any more. To fix this, make xfs_attr_inactive() completely remove all traces of the attribute fork from the inode, regardless of it's state. Further, also remove the in-core attribute fork structure safely so that there is nothing further that needs to be done by callers to clean up the attribute fork. This means we can remove the in-core and on-disk attribute forks atomically. Also, on error simply remove the in-memory attribute fork. There's nothing that can be done with it once we have failed to remove the on-disk attribute fork, so we may as well just blow it away here anyway. Reported-by:

commit 3530febb upstream. This reverts commit 7290006d. Through the regression report, it was revealed that the tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the mute LED but actually mutes the sound. This is contradiction to the expectation, and rather confuses user. According to Henrique, it's not trivial to judge which TP model behaves "LED-only" and which model does whatever more intrusive, as Lenovo's implementations vary model by model. So, from the safety reason, we should revert the patch for now. Reported-by:

commit 2e7f43c4 upstream. In commit f02ad907 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Jan 22 16:36:23 2015 +0100 drm/atomic-helpers: Recover full cursor plane behaviour we've added a hack to atomic helpers to never to vblank waits for cursor updates through the legacy apis since that's what X expects. Unfortunately we've (again) forgotten to adjust the transitional helpers. Do this now. This fixes regressions for drivers only partially converted over to atomic (like i915). Reported-by:

commit a500e469 upstream. If the device is reset during suspend with net-detect enabled, we leave the net-detect information dangling and this causes the next suspend to fail with a warning: [21795.351010] WARNING: at /root/iwlwifi/iwlwifi-stack-dev/drivers/net/wireless/iwlwifi/mvm/d3.c:989 __iwl_mvm_suspend.isra.6+0x2be/0x460 [iwlmvm]() [21795.353253] Modules linked in: iwlmvm(O) iwlwifi(O) mac80211(O) cfg80211(O) compat(O) [...] [21795.366168] CPU: 1 PID: 3645 Comm: bash Tainted: G O 3.10.29-dev #1 [21795.368785] Hardware name: Dell Inc.
