The 2015 series of the Lenovo thinkpads added back the hardware buttons on top of the touchpad for the trackstick. Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons" touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay! Instead of manually removing each of the new ones, or hoping that we know all the current ones, we can consider that the PNPIDs list that were given contains touchpads that have the trackstick buttons, either physically wired to them, or emulated with the top software button property. Thanks to the extra buttons capability in query $10, we can reliably detect the physical buttons from the software ones, and so we can remove the TOPBUTTONPAD property even if it was declared as such.

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.

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:

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.

Query the min dimensions even if the check SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 7 fails, but we know that the firmware version 8.1 is safe. With that we don't need quirks for post-2013 models anymore as they expose correct min and max dimensions.

Merge tag 'trace-fixes-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull ftrace fixes from Steven Rostedt: "During testing Sedat Dilek hit a "suspicious RCU usage" splat that pointed out a real bug. During suspend and resume the tlb_flush tracepoint is called when the CPU is going offline. As the CPU has been noted as offline, RCU is ignoring that CPU, which means that it can not use RCU protected locks. When tracepoints are activated, they require RCU locking, and if RCU is ignoring a CPU that runs a tracepoint, there is a chance that the tracepoint could cause corruption. The solution was to change the tracepoint into a TRACE_EVENT_CONDITION() which allows us to check a condition to determine if the tracepoint should be called or not. If the condition is not met, the rcu protected code will not be executed. By adding the condition "cpu_online(smp_processor_id())", this will prevent the RCU protected code from being executed if the CPU is marked offline. After adding this, another bug was discovered. As RCU checks rcu callers, if a rcu call is not done, there is no check (obviously). We found that tracepoints could be added in RCU ignored locations and not have lockdep complain until the tracepoint is activated. This missed places where tracepoints were added in places they should not have been. To fix this, code was added in 3.18 that if lockdep is enabled, any tracepoint will still call the rcu checks even if the tracepoint is not enabled. The bug here, is that the check does not take the CONDITION into account. As the condition may prevent tracepoints from being activated in RCU ignored areas (as the one patch does), we get false positives when we enable lockdep and hit a tracepoint that the condition prevents it from being called in a RCU ignored location. The fix for this is to add the CONDITION to the rcu checks, even if the tracepoint is not enabled" * tag 'trace-fixes-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: x86/tlb/trace: Do not trace on CPU that is offline tracing: Add condition check to RCU lockdep checks

When taking a CPU down for suspend and resume, a tracepoint may be called when the CPU has been designated offline. As tracepoints require RCU for protection, they must not be called if the current CPU is offline. Unfortunately, trace_tlb_flush() is called in this scenario as was noted by LOCKDEP: ...

The trace_tlb_flush() tracepoint can be called when a CPU is going offline. When a CPU is offline, RCU is no longer watching that CPU and since the tracepoint is protected by RCU, it must not be called. To prevent the tlb_flush tracepoint from being called when the CPU is offline, it was converted to a TRACE_EVENT_CONDITION where the condition checks if the CPU is online before calling the tracepoint. Unfortunately, this was not enough to stop lockdep from complaining about it. Even though the RCU protected code of the tracepoint will never be called, the condition is hidden within the tracepoint, and even though the condition prevents RCU code from being called, the lockdep checks are outside the tracepoint (this is to test tracepoints even when they are not enabled). Even though tracepoints should be checked to be RCU safe when they are not enabled, the condition should still be considered when checking RCU.

While commit 7e36ef82 ("IB/core: Temporarily disable ex_query_device uverb") is correct as it makes the extended QUERY_DEVICE uverb (which came as part of commit 5a77abf9 ("IB/core: Add support for extended query device caps") and commit 860f10a7 ("IB/core: Add flags for on demand paging support")) not available to userspace, it doesn't address the initial issue regarding ib_copy_to_udata() [1][2]. Additionally, further discussions around this new uverb seems to conclude it would require a different data structure than the one currently described in <rdma/ib_user_verbs.h> [3]. Both of these issues require a revert of the changes, so this patch partially reverts commit 8cdd312c ("IB/mlx5: Implement the ODP capability query verb") and commit 860f10a7 ("IB/core: Add flags for on demand paging support") and fully reverts commit 5a77abf9 ("IB/core: Add support for extended query device caps").

Nilfs2 eventually hangs in a stress test with fsstress program. This issue was caused by the following deadlock over I_SYNC flag between nilfs_segctor_thread() and writeback_sb_inodes(): nilfs_segctor_thread() nilfs_segctor_thread_construct() nilfs_segctor_unlock() nilfs_dispose_list() iput() iput_final() evict() inode_wait_for_writeback() * wait for I_SYNC flag writeback_sb_inodes() * set I_SYNC flag on inode->i_state __writeback_single_inode() do_writepages() nilfs_writepages() nilfs_construct_dsync_segment() nilfs_segctor_sync() * wait for completion of segment constructor inode_sync_complete() * clear I_SYNC flag after __writeback_single_inode() completed writeback_sb_inodes() calls do_writepages() for dirty inodes after setting I_SYNC flag on inode->i_state. do_writepages() in turn calls nilfs_writepages(), which can run segment constructor and wait for its completion. On the other hand, segment constructor calls iput(), which can call evict() and wait for the I_SYNC flag on inode_wait_for_writeback(). Since segment constructor doesn't know when I_SYNC will be set, it cannot know whether iput() will block or not unless inode->i_nlink has a non-zero count. We can prevent evict() from being called in iput() by implementing sop->drop_inode(), but it's not preferable to leave inodes with i_nlink == 0 for long periods because it even defers file truncation and inode deallocation. So, this instead resolves the deadlock by calling iput() asynchronously with a workqueue for inodes with i_nlink == 0.

It has been reported that 965GM might trigger VM_BUG_ON_PAGE(!lrucare && PageLRU(oldpage), oldpage) in mem_cgroup_migrate when shmem wants to replace a swap cache page because of shmem_should_replace_page (the page is allocated from an inappropriate zone). shmem_replace_page expects that the oldpage is not on LRU list and calls mem_cgroup_migrate without lrucare. This is obviously incorrect because swapcache pages might be on the LRU list (e.g. swapin readahead page). Fix this by enabling lrucare for the migration in shmem_replace_page. Also clarify that lrucare should be used even if one of the pages might be on LRU list. The BUG_ON will trigger only when CONFIG_DEBUG_VM is enabled but even without that the migration code might leave the old page on an inappropriate memcg' LRU which is not that critical because the page would get removed with its last reference but it is still confusing.

walk_page_range() silently skips vma having VM_PFNMAP set, which leads to undesirable behaviour at client end (who called walk_page_range). Userspace applications get the wrong data, so the effect is like just confusing users (if the applications just display the data) or sometimes killing the processes (if the applications do something with misunderstanding virtual addresses due to the wrong data.) For example for pagemap_read, when no callbacks are called against VM_PFNMAP vma, pagemap_read may prepare pagemap data for next virtual address range at wrong index. Eventually userspace may get wrong pagemap data for a task. Corresponding to a VM_PFNMAP marked vma region, kernel may report mappings from subsequent vma regions. User space in turn may account more pages (than really are) to the task. In my case I was using procmem, procrack (Android utility) which uses pagemap interface to account RSS pages of a task. Due to this bug it was giving a wrong picture for vmas (with VM_PFNMAP set). Fixes: a9ff785e ("mm/pagewalk.c: walk_page_range should avoid VM_PFNMAP areas") Signed-off-by:

Merge tag 'asoc-fix-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v3.19 A few last minute fixes for v3.19, all driver specific. None of them stand out particularly - it's all the standard people who are affected will care stuff. The Samsung fix is a DT only fix for the audio controller, it's being merged via the ASoC tree due to process messups (the submitter sent it at the end of a tangentally related series rather than separately to the ARM folks) in order to make sure that it gets to people sooner.
