Changes to of_match_node matching caused the serial port on some PPC boards to stop working.

06b29e7 Kevin Hao 14 February 2014, 05:22:46 UTC of: search the best compatible match first in __of_match_node() Currently, of_match_node compares each given match against all node's compatible strings with of_device_is_compatible. To achieve multiple compatible strings per node with ordering from specific to generic, this requires given matches to be ordered from specific to generic. For most of the drivers this is not true and also an alphabetical ordering is more sane there. Therefore, this patch introduces a function to match each of the node's compatible strings against all given compatible matches without type and name first, before checking the next compatible string. This implies that node's compatibles are ordered from specific to generic while given matches can be in any order. If we fail to find such a match entry, then fall-back to the old method in order to keep compatibility.

The first is a fix for the way the ring buffer stores timestamps. After a restructure of the code was done, the ring buffer timestamp logic missed the fact that the first event on a sub buffer is to have a zero delta, as the full timestamp is stored on the sub buffer itself. But because the delta was not cleared to zero, the timestamp for that event will be calculated as the real timestamp + the delta from the last timestamp. This can skew the timestamps of the events and have them say they happened when they didn't really happen. That's bad. The second fix is for modifying the function graph caller site. When the stop machine was removed from updating the function tracing code, it missed updating the function graph call site location. It is still modified as if it is being done via stop machine. But it's not. This can lead to a GPF and kernel crash if the function graph call site happens to lie between cache lines and one CPU is executing it while another CPU is doing the update. It would be a very hard condition to hit, but the result is severe enough to have it fixed ASAP" * tag 'trace-fixes-v3.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace/x86: Use breakpoints for converting function graph caller ring-buffer: Fix first commit on sub-buffer having non-zero delta 15 February 2014, 23:03:34 UTC

93de4ba Filipe David Borba Manana 15 February 2014, 15:53:16 UTC Btrfs: use right clone root offset for compressed extents For non compressed extents, iterate_extent_inodes() gives us offsets that take into account the data offset from the file extent items, while for compressed extents it doesn't. Therefore we have to adjust them before placing them in a send clone instruction. Not doing this adjustment leads to the receiving end requesting for a wrong a file range to the clone ioctl, which results in different file content from the one in the original send root.

79970db Wolfram Sang 13 February 2014, 20:36:29 UTC i2c: mv64xxx: refactor message start to ensure proper initialization Because the offload mechanism can fall back to a standard transfer, having two seperate initialization states is unfortunate. Let's just have one state which does things consistently. This fixes a bug where some preparation was missing when the fallback happened. And it makes the code much easier to follow. To implement this, we put the check if offload is possible at the top of the offload setup function.

3a0dfa6 Josef Bacik 14 February 2014, 18:43:48 UTC Btrfs: unset DCACHE_DISCONNECTED when mounting default subvol A user was running into errors from an NFS export of a subvolume that had a default subvol set. When we mount a default subvol we will use d_obtain_alias() to find an existing dentry for the subvolume in the case that the root subvol has already been mounted, or a dummy one is allocated in the case that the root subvol has not already been mounted. This allows us to connect the dentry later on if we wander into the path. However if we don't ever wander into the path we will keep DCACHE_DISCONNECTED set for a long time, which angers NFS. It doesn't appear to cause any problems but it is annoying nonetheless, so simply unset DCACHE_DISCONNECTED in the get_default_root case and switch btrfs_lookup() to use d_materialise_unique() instead which will make everything play nicely together and reconnect stuff if we wander into the defaul subvol path from a different way. With this patch I'm no longer getting the NFS errors when exporting a volume that has been mounted with a default subvol set.

Any other value that is supplied to max_inline will be adjusted to a minimum of 4k. Since max_inline has an effective maximum of ~3900 bytes due to page size limitations, the current behaviour only has meaning for max_inline=0.

So it's different with __btrfs_run_delayed_refs(), where we do drop-acquire dance before and after actually processing delayed refs. Here we don't drop the lock, others are not able to add new delayed refs to head_ref, so cond_resched_lock(&head_ref->lock) is not necessary here.

This provides better user experience for legacy applications that don't use the RDMA CM and were working on index 0 prior to the IP addressing change. Also, as GIDs are generated from IP addresses of the network devices that are associated with the port, it's basically possible that the GID table will be empty if no IP address was assigned.

dd5fd9b Thomas Gleixner 11 February 2014, 13:35:40 UTC tick: Clear broadcast pending bit when switching to oneshot AMD systems which use the C1E workaround in the amd_e400_idle routine trigger the WARN_ON_ONCE in the broadcast code when onlining a CPU. The reason is that the idle routine of those AMD systems switches the cpu into forced broadcast mode early on before the newly brought up CPU can switch over to high resolution / NOHZ mode. The timer related CPU1 bringup looks like this: clockevent_register_device(local_apic); tick_setup(local_apic); ... idle() tick_broadcast_on_off(FORCE); tick_broadcast_oneshot_control(ENTER) cpumask_set(cpu, broadcast_oneshot_mask); halt(); Now the broadcast interrupt on CPU0 sets CPU1 in the broadcast_pending_mask and wakes CPU1. So CPU1 continues: local_apic_timer_interrupt() tick_handle_periodic(); softirq() tick_init_highres(); cpumask_clr(cpu, broadcast_oneshot_mask); tick_broadcast_oneshot_control(ENTER) WARN_ON(cpumask_test(cpu, broadcast_pending_mask); So while we remove CPU1 from the broadcast_oneshot_mask when we switch over to highres mode, we do not clear the pending bit, which then triggers the warning when we go back to idle. The reason why this is only visible on C1E affected AMD systems is that the other machines enter the deep sleep states via acpi_idle/intel_idle and exit the broadcast mode before executing the remote triggered local_apic_timer_interrupt. So the pending bit is already cleared when the switch over to highres mode is clearing the oneshot mask. The solution is simple: Clear the pending bit together with the mask bit when we switch over to highres mode. Stanislaw came up independently with the same patch by enforcing the C1E workaround and debugging the fallout.

2ec197d NeilBrown 07 February 2014, 06:10:26 UTC lockd: send correct lock when granting a delayed lock. If an NFS client attempts to get a lock (using NLM) and the lock is not available, the server will remember the request and when the lock becomes available it will send a GRANT request to the client to provide the lock. If the client already held an adjacent lock, the GRANT callback will report the union of the existing and new locks, which can confuse the client. This happens because __posix_lock_file (called by vfs_lock_file) updates the passed-in file_lock structure when adjacent or over-lapping locks are found. To avoid this problem we take a copy of the two fields that can be changed (fl_start and fl_end) before the call and restore them afterwards. An alternate would be to allocate a 'struct file_lock', initialise it, use locks_copy_lock() to take a copy, then locks_release_private() after the vfs_lock_file() call. But that is a lot more work.

Peter Anvin 13 February 2014, 15:46:04 UTC x86, smap: smap_violation() is bogus if CONFIG_X86_SMAP is off If CONFIG_X86_SMAP is disabled, smap_violation() tests for conditions which are incorrect (as the AC flag doesn't matter), causing spurious faults. The dynamic disabling of SMAP (nosmap on the command line) is fine because it disables X86_FEATURE_SMAP, therefore causing the static_cpu_has() to return false. Found by Fengguang Wu's test system.

a9f1803 Steven Noonan 13 February 2014, 07:01:07 UTC compiler/gcc4: Make quirk for asm_volatile_goto() unconditional I started noticing problems with KVM guest destruction on Linux 3.12+, where guest memory wasn't being cleaned up. I bisected it down to the commit introducing the new 'asm goto'-based atomics, and found this quirk was later applied to those. Unfortunately, even with GCC 4.8.2 (which ostensibly fixed the known 'asm goto' bug) I am still getting some kind of miscompilation. If I enable the asm_volatile_goto quirk for my compiler, KVM guests are destroyed correctly and the memory is cleaned up. So make the quirk unconditional for now, until bug is found and fixed.

789b5e0 Oleg Nesterov 05 February 2014, 22:12:45 UTC md/raid5: Fix CPU hotplug callback registration Subsystems that want to register CPU hotplug callbacks, as well as perform initialization for the CPUs that are already online, often do it as shown below: get_online_cpus(); for_each_online_cpu(cpu) init_cpu(cpu); register_cpu_notifier(&foobar_cpu_notifier); put_online_cpus(); This is wrong, since it is prone to ABBA deadlocks involving the cpu_add_remove_lock and the cpu_hotplug.lock (when running concurrently with CPU hotplug operations). Interestingly, the raid5 code can actually prevent double initialization and hence can use the following simplified form of callback registration: register_cpu_notifier(&foobar_cpu_notifier); get_online_cpus(); for_each_online_cpu(cpu) init_cpu(cpu); put_online_cpus(); A hotplug operation that occurs between registering the notifier and calling get_online_cpus(), won't disrupt anything, because the code takes care to perform the memory allocations only once. So reorganize the code in raid5 this way to fix the deadlock with callback registration.
