[ Upstream commit 87f966d9 ] On a MIPS Malta board, tons of fifo underflow errors have been observed when using u-boot as bootloader instead of YAMON. The reason for that is that YAMON used to set the pcnet device to SRAM mode but u-boot does not. As a result, the default Tx threshold (64 bytes) is now too small to keep the fifo relatively used and it can result to Tx fifo underflow errors. As a result of which, it's best to setup the SRAM on supported controllers so we can always use the NOUFLO bit.

[ Upstream commit f6ff0414 ] We currently use the device tree update code in the kernel after resuming from a suspend operation to re-sync the kernels view of the device tree with that of the hypervisor. The code as it stands is not endian safe as it relies on parsing buffers returned by RTAS calls that thusly contains data in big endian format. This patch annotates variables and structure members with __be types as well as performing necessary byte swaps to cpu endian for data that needs to be parsed. Signed-off-by:

[ Upstream commit 44d5f6f5 ] commit id 2ba9f0d8 has changed CONFIG_KVM_BOOK3S_64_HV to tristate to allow HV/PR bits to be built as modules. But the MCE code still depends on CONFIG_KVM_BOOK3S_64_HV which is wrong. When user selects CONFIG_KVM_BOOK3S_64_HV=m to build HV/PR bits as a separate module the relevant MCE code gets excluded. This patch fixes the MCE code to use CONFIG_KVM_BOOK3S_64_HANDLER. This makes sure that the relevant MCE code is included when HV/PR bits are built as a separate modules.

[ Upstream commit f7cf2a22 ] Haswell moved the TOLM/TOHM registers to a different device and offset. The sb_edac driver accounted for the change of device, but not for the new offset. There was also a typo in the constant to fill in the low 26 bits (was 0x1ffffff, should be 0x3ffffff).

[ Upstream commit 6d7fdb0a ] This reverts commit 89baaa57. Dirty page throttling should be sufficient for us in the general case so there is no need to use __GFP_MEMALLOC - it would be needed only in the swap-over-rbd case, which we currently don't support. (It would probably take approximately the commit that is being reverted to add that support, but we would also need the "swap" option to distinguish from the general case and make sure swap ceph_client-s aren't shared with anything else.) See ceph-devel threads [1] and [2] for the details of why enabling pfmemalloc reserves for all cases is a bad thing. On top of potential system lockups related to drained emergency reserves, this turned out to cause ceph lockups in case peers are on the same host and communicating via loopback due to sk_filter() dropping pfmemalloc skbs on the receiving side because the receiving loopback socket is not tagged with SOCK_MEMALLOC.

[ Upstream commit 98cf21c6 ] Fix B-tree corruption when a new record is inserted at position 0 in the node in hfs_brec_insert(). In this case a hfs_brec_update_parent() is called to update the parent index node (if exists) and it is passed hfs_find_data with a search_key containing a newly inserted key instead of the key to be updated. This results in an inconsistent index node. The bug reproduces on my machine after an extents overflow record for the catalog file (CNID=4) is inserted into the extents overflow B-tree. Because of a low (reserved) value of CNID=4, it has to become the first record in the first leaf node. The resulting first leaf node is correct: ---------------------------------------------------- | key0.CNID=4 | key1.CNID=123 | key2.CNID=456, ... | ---------------------------------------------------- But the parent index key0 still contains the previous key CNID=123: ----------------------- | key0.CNID=123 | ... | ----------------------- A change in hfs_brec_insert() makes hfs_brec_update_parent() work correctly by preventing it from getting fd->record=-1 value from __hfs_brec_find(). Along the way, I removed duplicate code with unification of the if condition. The resulting code is equivalent to the original code because node is never 0. Also hfs_brec_update_parent() will now return an error after getting a negative fd->record value. However, the return value of hfs_brec_update_parent() is not checked anywhere in the file and I'm leaving it unchanged by this patch. brec.c lacks error checking after some other calls too, but this issue is of less importance than the one being fixed by this patch.

[ Upstream commit 09ee96b2 ] The "dm snapshot: suspend origin when doing exception handover" commit fixed a exception store handover bug associated with pending exceptions to the "snapshot-origin" target. However, a similar problem exists in snapshot merging. When snapshot merging is in progress, we use the target "snapshot-merge" instead of "snapshot-origin". Consequently, during exception store handover, we must find the snapshot-merge target and suspend its associated mapped_device. To avoid lockdep warnings, the target must be suspended and resumed without holding _origins_lock. Introduce a dm_hold() function that grabs a reference on a mapped_device, but unlike dm_get(), it doesn't crash if the device has the DMF_FREEING flag set, it returns an error in this case. In snapshot_resume() we grab the reference to the origin device using dm_hold() while holding _origins_lock (_origins_lock guarantees that the device won't disappear). Then we release _origins_lock, suspend the device and grab _origins_lock again. NOTE to stable@ people: When backporting to kernels 3.18 and older, use dm_internal_suspend and dm_internal_resume instead of dm_internal_suspend_fast and dm_internal_resume_fast. Signed-off-by:

[ Upstream commit b735fede ] In the function snapshot_resume we perform exception store handover. If there is another active snapshot target, the exception store is moved from this target to the target that is being resumed. The problem is that if there is some pending exception, it will point to an incorrect exception store after that handover, causing a crash due to dm-snap-persistent.c:get_exception()'s BUG_ON. This bug can be triggered by repeatedly changing snapshot permissions with "lvchange -p r" and "lvchange -p rw" while there are writes on the associated origin device. To fix this bug, we must suspend the origin device when doing the exception store handover to make sure that there are no pending exceptions: - introduce _origin_hash that keeps track of dm_origin structures. - introduce functions __lookup_dm_origin, __insert_dm_origin and __remove_dm_origin that manipulate the origin hash. - modify snapshot_resume so that it calls dm_internal_suspend_fast() and dm_internal_resume_fast() on the origin device. NOTE to stable@ people: When backporting to kernels 3.12-3.18, use dm_internal_suspend and dm_internal_resume instead of dm_internal_suspend_fast and dm_internal_resume_fast. When backporting to kernels older than 3.12, you need to pick functions dm_internal_suspend and dm_internal_resume from the commit fd2ed4d2. Signed-off-by:

[ Upstream commit 5f027a3b ] It was always intended that a read to an unprovisioned block will return zeroes regardless of whether the pool is in read-only or read-write mode. thin_bio_map() was inconsistent with its handling of such reads when the pool is in read-only mode, it now properly zero-fills the bios it returns in response to unprovisioned block reads. Eliminate thin_bio_map()'s special read-only mode handling of -ENODATA and just allow the IO to be deferred to the worker which will result in pool->process_bio() handling the IO (which already properly zero-fills reads to unprovisioned blocks).

[ Upstream commit 0f611d28 ] Since moving the interface combination checks to mac80211, it's broken because it now only considers interfaces with an assigned channel context, so for example any interface that isn't active can still be up, which is clearly an issue; also, in particular P2P-Device wdevs are an issue since they never have a chanctx. Fix this by counting running interfaces instead the ones with a channel context assigned.

[ Upstream commit aa75ebc2 ] Some APs experience problems when working with U-APSD. Decreasing the probability of that happening by using legacy mode for all ACs but VO isn't enough. Cisco 4410N originally forced us to enable VO by default only because it treated non-VO ACs as legacy. However some APs (notably Netgear R7000) silently reclassify packets to different ACs. Since u-APSD ACs require trigger frames for frame retrieval clients would never see some frames (e.g. ARP responses) or would fetch them accidentally after a long time. It makes little sense to enable u-APSD queues by default because it needs userspace applications to be aware of it to actually take advantage of the possible additional powersavings. Implicitly depending on driver autotrigger frame support doesn't make much sense. Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit 496fcc29 ] As HT/VHT depend heavily on QoS/WMM, it's not a good idea to let userspace add clients that have HT/VHT but not QoS/WMM. Since it does so in certain cases we've observed (client is using HT IEs but not QoS/WMM) just ignore the HT/VHT info at this point and don't pass it down to the drivers which might unconditionally use it.

[ Upstream commit ebc80840 ] The Fimware 8.1 has a bug in which the extra buttons are only sent when the ExtBit is 1. This should be fixed in a future FW update which should have a bump of the minor version. Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit dc5465dc ] On the X1 Carbon 3rd gen (with a 2015 broadwell cpu), the physical middle button of the trackstick (attached to the touchpad serio device, of course) seems to get lost. Actually, the touchpads reports 3 extra buttons, which falls in the switch below to the '2' case. Let's handle the case of odd numbers also, so that the middle button finds its way back.

[ Upstream commit 02e07492 ] Post-2013 Lenovo laptops provide correct min/max dimensions, which are different with the ones currently quirked. According to https://bugzilla.kernel.org/show_bug.cgi?id=91541 the following board ids are assigned in the post-2013 touchpads: t440p/t440s: LEN0036 -> 2964/2962 t540p: LEN0034 -> 2964 Using 2961 as the common minimum makes these 3 laptops OK. We may need to update those values later if other pnp_ids has a lower board_id. Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit 5b3089dd ] Add a min/max range for board ids to the min/max coordinates quirk. This makes it possible to restrict quirks to specific models based upon their board id.
