The interrupt handler in the driver tries to fetch driver data from platform device, unfortunately it is only set up after interrupt handler is registered. Since interrupt handler does not really need to access the platform device itself let's change it to get the driver data instance instead.

2015-02-15Input: ALPS - do not mix trackstick and external PS/2 mouse dataPali Rohár2-53/+151
Previously dev2 device was used for both external PS/2 mouse and internal trackstick device (if available). This change introduces dev3 device which is used for external PS/2 mouse data and dev2 is now used only for trackstick. In case that trackstick is not present dev2 is not created, so userspace does not see non existent device in system. Because laptops with ALPS devices often do not use i8042 active multiplexing all data (from touchpad, trackstick and external PS/2 mouse) come to one port. So it is not possible to know if external PS/2 mouse is connected or not. In most cases external PS/2 mouse is not connected so driver will create dev3 input device after first bare PS/2 packet will be received. So there will not be "ghost" input device. This change also helps in identifying possible problems in future if driver decides to report 6-bytes trackstick packets as 3-bytes bare PS/2 (data will be reported to dev3 instead dev2).

2015-02-15Input: ALPS - fix trackstick detection on some Dell LatitudesDmitry Torokhov1-22/+56
On some Dell Latitudes we fail to identify presence of trackstick unless we reset the device. The issue is quite benign as we do perform reset in alps_init(), so the trackstick ends up working, but mouse name reported to userspace is not accurate. In order to fix the issue while avoiding the additional lengthy reset we move the resrt to alps_detect() and keep the discovered state to be used later in alps_init().

GNOME can already make use of the Windows key on multiple form factors, and other desktop environments can use it depending on the form factor.

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: ...

2015-02-07tracing: Add condition check to RCU lockdep checksSteven Rostedt (Red Hat)1-1/+1
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.

2015-02-06Revert "IB/core: Add support for extended query device caps"Yann Droneaud5-130/+42
While commit 7e36ef8205ff ("IB/core: Temporarily disable ex_query_device uverb") is correct as it makes the extended QUERY_DEVICE uverb (which came as part of commit 5a77abf9a97a ("IB/core: Add support for extended query device caps") and commit 860f10a799c8 ("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 8cdd312cfed7 ("IB/mlx5: Implement the ODP capability query verb") and commit 860f10a799c8 ("IB/core: Add flags for on demand paging support") and fully reverts commit 5a77abf9a97a ("IB/core: Add support for extended query device caps").

2015-02-05nilfs2: fix deadlock of segment constructor over I_SYNC flagRyusuke Konishi3-7/+44
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.

2015-02-05memcg, shmem: fix shmem migration to use lrucareMichal Hocko2-2/+2
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.

2015-02-05mm: pagewalk: call pte_hole() for VM_PFNMAP during walk_page_rangeShiraz Hashim1-1/+4
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).

2015-02-05IRQCHIP: mips-gic: Avoid rerouting timer IRQs for smp-cmpJames Hogan1-0/+27
Commit e9de688dac65 ("irqchip: mips-gic: Support local interrupts") changed the GIC irqchip driver so that all local interrupts were routed to the same CPU pin used for external interrupts. Unfortunately this causes a regression when smp-cmp is used. The CPUs are started by the bootloader and put in a timer based waiting poll loop, but when their timer interrupts are rerouted to a different IRQ pin which is not unmasked they never wake up. Since smp-cmp support is deprecated and everybody who was using it should be switching to smp-cps which brings up the secondary CPUs without bootloader assistance, I've gone for the simple fix which can be easily removed once smp-cmp is removed, rather than a fully generic fix.

2015-02-05hrtimer: Fix incorrect tai offset calculation for non high-res timer systemsJohn Stultz1-1/+1
I noticed some CLOCK_TAI timer test failures on one of my less-frequently used configurations. And after digging in I found in 76f4108892d9 (Cleanup hrtimer accessors to the timekepeing state), the hrtimer_get_softirq_time tai offset calucation was incorrectly rewritten, as the tai offset we return shold be from CLOCK_MONOTONIC, and not CLOCK_REALTIME. This results in CLOCK_TAI timers expiring early on non-highres capable machines. This patch fixes the issue, calculating the tai time properly from the monotonic base.

2015-02-04cls_api.c: Fix dumping of non-existing actions' stats.Ignacy Gawędzki1-3/+4
In tcf_exts_dump_stats(), ensure that exts->actions is not empty before accessing the first element of that list and calling tcf_action_copy_stats() on it. This fixes some random segvs when adding filters of type "basic" with no particular action. This also fixes the dumping of those "no-action" filters, which more often than not made calls to tcf_action_copy_stats() fail and consequently netlink attributes added by the caller to be removed by a call to nla_nest_cancel().

2015-02-05drm/cirrus: Limit modes depending on bpp optionTakashi Iwai4-2/+15
The commit [8975626ea35a: drm/cirrus: allow 32bpp framebuffers for cirrus drm] broke X modesetting driver because cirrus driver still provides the full list of modes up to 1280x1024 while the 32bpp can support only up to 800x600. We might be able to filter out the invalid modes in mode_valid callback, but unfortunately the bpp in question can't be referred there for now (let me know if there is a better way to retrieve the bpp for the probed fb). So, instead, this patch adds the bpp module option to specify the maximal bpp explicitly and limits the resolutions in get_modes depending on its value. The default value is set to 24 so that the existing stuff keeps working. If you need a new 32bpp feature, specify cirrus.bpp=32 option explicitly.
