commit dc5465dc upstream. 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.

commit 02e07492 upstream. 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. Signed-off-by:

commit 29d62ec5 upstream. Normally _regulator_do_enable() isn't called on an already-enabled rdev. That's because the main caller, _regulator_enable() always calls _regulator_is_enabled() and only calls _regulator_do_enable() if the rdev was not already enabled. However, there is one caller of _regulator_do_enable() that doesn't check: regulator_suspend_finish(). While we might want to make regulator_suspend_finish() behave more like _regulator_enable(), it's probably also a good idea to make _regulator_do_enable() robust if it is called on an already enabled rdev. At the moment, _regulator_do_enable() is _not_ robust for already enabled rdevs if we're using an ena_pin. Each time _regulator_do_enable() is called for an rdev using an ena_pin the reference count of the ena_pin is incremented even if the rdev was already enabled. This is not as intended because the ena_pin is for something else: for keeping track of how many active rdevs there are sharing the same ena_pin. Here's how the reference counting works here: * Each time _regulator_enable() is called we increment rdev->use_count, so _regulator_enable() calls need to be balanced with _regulator_disable() calls. * There is no explicit reference counting in _regulator_do_enable() which is normally just a warapper around rdev->desc->ops->enable() with code for supporting delays. It's not expected that the "ops->enable()" call do reference counting. * Since regulator_ena_gpio_ctrl() does have reference counting (handling the sharing of the pin amongst multiple rdevs), we shouldn't call it if the current rdev is already enabled. Note that as part of this we cleanup (remove) the initting of ena_gpio_state in regulator_register(). In _regulator_do_enable(), _regulator_do_disable() and _regulator_is_enabled() is is clear that ena_gpio_state should be the state of whether this particular rdev has requested the GPIO be enabled. regulator_register() was initting it as the actual state of the pin.

commit 0548bf4f upstream. The _regulator_do_enable() call ought to be a no-op when called on an already-enabled regulator. However, as an optimization _regulator_enable() doesn't call _regulator_do_enable() on an already enabled regulator. That means we never test the case of calling _regulator_do_enable() during normal usage and there may be hidden bugs or warnings. We have seen warnings issued by the tps65090 driver and bugs when using the GPIO enable pin. Let's match the same optimization that _regulator_enable() in regulator_suspend_finish(). That may speed up suspend/resume and also avoids exposing hidden bugs. [Use much clearer commit message from Doug Anderson] Signed-off-by:

commit e8932869 upstream. On gcc5 the kernel does not link: ld: .eh_frame_hdr table[4] FDE at 0000000000000648 overlaps table[5] FDE at 0000000000000670. Because prior GCC versions always emitted NOPs on ALIGN directives, but gcc5 started omitting them. .LSTARTFDEDLSI1 says: /* HACK: The dwarf2 unwind routines will subtract 1 from the return address to get an address in the middle of the presumed call instruction. Since we didn't get here via a call, we need to include the nop before the real start to make up for it. */ .long .LSTART_sigreturn-1-. /* PC-relative start address */ But commit 69d0627a ("x86 vDSO: reorder vdso32 code") from 2.6.25 replaced .org __kernel_vsyscall+32,0x90 by ALIGN right before __kernel_sigreturn. Of course, ALIGN need not generate any NOP in there. Esp. gcc5 collapses vclock_gettime.o and int80.o together with no generated NOPs as "ALIGN". So fix this by adding to that point at least a single NOP and make the function ALIGN possibly with more NOPs then. Kudos for reporting and diagnosing should go to Richard. Reported-by:

commit 7b8f10da upstream. The initialisation of the efm32 clocksource first sets up the irq and only after that initialises the data needed for irq handling. In case this initialisation is delayed the irq handler would dereference a NULL pointer. I'm not aware of anything that could delay the process in such a way, but it's better to be safe than sorry, so setup the irq only when the clock event device is ready. Acked-by:

commit aa75ebc2 upstream. 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. Signed-off-by:

commit 001eabfd upstream. This updates the bit sliced AES module to the latest version in the upstream OpenSSL repository (e620e5ae37bc). This is needed to fix a bug in the XTS decryption path, where data chunked in a certain way could trigger the ciphertext stealing code, which is not supposed to be active in the kernel build (The kernel implementation of XTS only supports round multiples of the AES block size of 16 bytes, whereas the conformant OpenSSL implementation of XTS supports inputs of arbitrary size by applying ciphertext stealing). This is fixed in the upstream version by adding the missing #ifndef XTS_CHAIN_TWEAK around the offending instructions. The upstream code also contains the change applied by Russell to build the code unconditionally, i.e., even if __LINUX_ARM_ARCH__ < 7, but implemented slightly differently.

commit 09ee96b2 upstream. 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:

commit b735fede upstream. 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:
