Pull GFS2 updates from Steven Whitehouse: "This is one of the smallest collections of patches for the merge window for some time. There are some clean ups relating to the transaction code and the shrinker, which are mostly in preparation for further development, but also make the code much easier to follow in these areas. There is a patch which allows the use of ->writepages even in the default ordered write mode for all writebacks. This results in sending larger i/os to the block layer, and a subsequent increase in performance. It also reduces the number of different i/o paths by one. There is also a bug fix reinstating the withdraw ack system which somehow got lost when the lock modules were merged into GFS2." * git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw: GFS2: Reinstate withdraw ack system GFS2: Get a block reservation before resizing a file GFS2: Split glock lru processing into two parts GFS2: Use ->writepages for ordered writes GFS2: Clean up freeze code GFS2: Merge gfs2_attach_bufdata() into trans.c GFS2: Copy gfs2_trans_add_bh into new data/meta functions GFS2: Split gfs2_trans_add_bh() into two GFS2: Merge revoke adding functions GFS2: Separate LRU scanning from shrinker

2013-02-21KEYS: Revert one application of "Fix unreachable code" patchDavid Howells
A patch to fix some unreachable code in search_my_process_keyrings() got applied twice by two different routes upstream as commits e67eab39bee2 and b010520ab3d2 (both "fix unreachable code"). Unfortunately, the second application removed something it shouldn't have and this wasn't detected by GIT. This is due to the patch not having sufficient lines of context to distinguish the two places of application. The effect of this is relatively minor: inside the kernel, the keyring search routines may search multiple keyrings and then prioritise the errors if no keys or negative keys are found in any of them. With the extra deletion, the presence of a negative key in the thread keyring (causing ENOKEY) is incorrectly overridden by an error searching the process keyring. So revert the second application of the patch.

2013-02-21ALSA: usb: Fix Processing Unit Descriptor parsersPawel Moll
Commit 99fc86450c439039d2ef88d06b222fd51a779176 "ALSA: usb-mixer: parse descriptors with structs" introduced a set of useful parsers for descriptors. Unfortunately the parses for the Processing Unit Descriptor came with a very subtle bug... Functions uac_processing_unit_iProcessing() and uac_processing_unit_specific() were indexing the baSourceID array forgetting the fields before the iProcessing and process-specific descriptors. The problem was observed with Sound Blaster Extigy mixer, where nNrModes in Up/Down-mix Processing Unit Descriptor was accessed at offset 10 of the descriptor (value 0) instead of offset 15 (value 7). In result the resulting control had interesting limit values: Simple mixer control 'Channel Routing Mode Select',0 Capabilities: volume volume-joined penum Playback channels: Mono Capture channels: Mono Limits: 0 - -1 Mono: -1 [100%] Fixed by starting from the bmControls, which was calculated correctly, instead of baSourceID. Now the mentioned control is fine: Simple mixer control 'Channel Routing Mode Select',0 Capabilities: volume volume-joined penum Playback channels: Mono Capture channels: Mono Limits: 0 - 6 Mono: 0 [0%] Signed-off-by: Pawel Moll <mail@pawelmoll.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Pull networking update from David Miller: 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP timestamp offset. From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

2013-02-20sparc64: Fix huge PMD to PTE translation for sun4u in TLB miss handler.David S. Miller
When we set the sun4u version of the PTE execute bit, it's: or REG, _PAGE_EXEC_4U, REG _PAGE_EXEC_4U is 0x1000, unfortunately the immedate field of the 'or' instruction is a signed 13-bit value. So the above actually assembles into: or REG, -4096, REG completely corrupting the final PTE value. Set it with a: sethi %hi(_PAGE_EXEC_4U), TMP or REG, TMP, REG sequence instead. This fixes "git gc" crashes on sun4u machines. Reported-by: Meelis Roos <mroos@linux.ee> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-02-20sparc64: Fix tsb_grow() in atomic context.David S. Miller
If our first THP installation for an MM is via the set_pmd_at() done during khugepaged's collapsing we'll end up in tsb_grow() trying to do a GFP_KERNEL allocation with several locks held. Simply using GFP_ATOMIC in this situation is not the best option because we really can't have this fail, so we'd really like to keep this an order 0 GFP_KERNEL allocation if possible. Also, doing the TSB allocation from khugepaged is a really bad idea because we'll allocate it potentially from the wrong NUMA node in that context. So what we do is defer the hugepage TSB allocation until the first TLB miss we take on a hugepage. This is slightly tricky because we have to handle two unusual cases: 1) Taking the first hugepage TLB miss in the window trap handler. We'll call the winfix_trampoline when that is detected. 2) An initial TSB allocation via TLB miss races with a hugetlb fault on another cpu running the same MM. We handle this by unconditionally loading the TSB we see into the current cpu even if it's non-NULL at hugetlb_setup time. Reported-by: Meelis Roos <mroos@ut.ee> Signed-off-by: David S.

All is ACKed by Greg, after a long discussion about different alternatives. - Some stuff also touches the MFD and ARM SoC trees, this has been coordinated and ACKed. - New drivers for: - The Tegra 114 sub-SoC - Allwinner sunxi - New ABx500 driver and sub-SoC drivers for AB8500, AB8505, AB9540 and AB8540. - Make it possible for hogged pins to enter a sleep mode, and make it possible for drivers to control that mode. - Various clean-up, extensions and device tree support to various pin controllers." * tag 'pinctrl-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (68 commits) pinctrl: tegra: add clfvs function to Tegra114 support pinctrl: generic: rename input schmitt disable pinctrl/pinconfig: add debug interface pinctrl: samsung: remove duplicated line ARM: ux500: use real AB8500 IRQ numbers instead of virtual ones ARM: ux500: remove irq_base property from platform_data pinctrl/abx500: use direct IRQ defines pinctrl/abx500: replace IRQ offsets with table read-in values pinctrl/abx500: move IRQ handling to ab8500-core pinctrl: exynos5440: remove erroneous __init pinctrl/abx500: adjust offset for get_mode() pinctrl/abx500: add Device Tree support pinctrl/abx500: align GPIO cluster boundaries pinctrl/abx500: prevent error path from corrupting returning error pinctrl: sunxi: add of_xlate function pinctrl/lantiq: fix pin number in ltq_pmx_gpio_request_enable pinctrl/lantiq: add functionality to falcon_pinconf_dbg_show pinctrl/lantiq: fix pinconfig parameters pinctrl/lantiq: one of the boot leds was defined incorrectly pinctrl/lantiq: only probe available pad controllers ...

After this change, there only remain a couple of mostly trivial dependencies on cgroup_lock outside cgroup core proper. cgroup_lock is scheduled to be unexported in this devel cycle. This will finally remove the fragile locking order around cgroup (cgroup locking wants to / should be one of the outermost but yet has been acquired from deep inside individual controllers). - At this point, Li is most knowlegeable with cpuset and taking over the maintainership of cpuset. * 'for-3.9-cpuset' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cpuset: drop spurious retval assignment in proc_cpuset_show() cpuset: fix RCU lockdep splat cpuset: update MAINTAINERS cpuset: remove cpuset->parent cpuset: replace cpuset->stack_list with cpuset_for_each_descendant_pre() cpuset: replace cgroup_mutex locking with cpuset internal locking cpuset: schedule hotplug propagation from cpuset_attach() if the cpuset is empty cpuset: pin down cpus and mems while a task is being attached cpuset: make CPU / memory hotplug propagation asynchronous cpuset: drop async_rebuild_sched_domains() cpuset: don't nest cgroup_mutex inside get_online_cpus() cpuset: reorganize CPU / memory hotplug handling cpuset: cleanup cpuset[_can]_attach() cpuset: introduce cpuset_for_each_child() cpuset: introduce CS_ONLINE cpuset: introduce ->css_on/offline() cpuset: remove fast exit path from remove_tasks_in_empty_cpuset() cpuset: remove unused cpuset_unlock()

Pull workqueue changes from Tejun Heo: "A lot of reorganization is going on mostly to prepare for worker pools with custom attributes so that workqueue can replace custom pool implementations in places including writeback and btrfs and make CPU assignment in crypto more flexible. workqueue evolved from purely per-cpu design and implementation, so there are a lot of assumptions regarding being bound to CPUs and even unbound workqueues are implemented as an extension of the model - workqueues running on the special unbound CPU. Bulk of changes this round are about promoting worker_pools as the top level abstraction replacing global_cwq (global cpu workqueue). At this point, I'm fairly confident about getting custom worker pools working pretty soon and ready for the next merge window. Lai's patches are replacing the convoluted mb() dancing workqueue has been doing with much simpler mechanism which only depends on assignment atomicity of long. For details, please read the commit message of 0b3dae68ac ("workqueue: simplify is-work-item-queued-here test"). While the change ends up adding one pointer to struct delayed_work, the inflation in percentage is less than five percent and it decouples delayed_work logic a lot more cleaner from usual work handling, removes the unusual memory barrier dancing, and allows for further simplification, so I think the trade-off is acceptable. There will be two more workqueue related pull requests and there are some shared commits among them. I'll write further pull requests assuming this pull request is pulled first." * 'for-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (37 commits) workqueue: un-GPL function delayed_work_timer_fn() workqueue: rename cpu_workqueue to pool_workqueue workqueue: reimplement is_chained_work() using current_wq_worker() workqueue: fix is_chained_work() regression workqueue: pick cwq instead of pool in __queue_work() workqueue: make get_work_pool_id() cheaper workqueue: move nr_running into worker_pool workqueue: cosmetic update in try_to_grab_pending() workqueue: simplify is-work-item-queued-here test workqueue: make work->data point to pool after try_to_grab_pending() workqueue: add delayed_work->wq to simplify reentrancy handling workqueue: make work_busy() test WORK_STRUCT_PENDING first workqueue: replace WORK_CPU_NONE/LAST with WORK_CPU_END workqueue: post global_cwq removal cleanups workqueue: rename nr_running variables workqueue: remove global_cwq workqueue: remove worker_pool->gcwq workqueue: replace for_each_worker_pool() with for_each_std_worker_pool() workqueue: make freezing/thawing per-pool workqueue: make hotplug processing per-pool ...
