2013-04-10dmaengine: omap-dma: Start DMA without delay for cyclic channelsPeter Ujfalusi
cyclic DMA is only used by audio which needs DMA to be started without a delay. If the DMA for audio is started using the tasklet we experience random channel switch (to be more precise: channel shift).

2013-04-08tcm_vhost: Initialize vq->last_used_idx when set endpointAsias He
This patch fixes guest hang when booting seabios and guest. [ 0.576238] scsi0 : Virtio SCSI HBA [ 0.616754] virtio_scsi virtio1: request:id 0 is not a head! vq->last_used_idx is initialized only when /dev/vhost-scsi is opened or closed. vhost_scsi_open -> vhost_dev_init() -> vhost_vq_reset() vhost_scsi_release() -> vhost_dev_cleanup -> vhost_vq_reset() So, when guest talks to tcm_vhost after seabios does, vq->last_used_idx still contains the old valule for seabios. This confuses guest. Fix this by calling vhost_init_used() to init vq->last_used_idx when we set endpoint. Signed-off-by: Asias He <asias@redhat.com> Acked-by: Michael S.

2013-04-08tcm_vhost: Use vq->private_data to indicate if the endpoint is setupAsias He
Currently, vs->vs_endpoint is used indicate if the endpoint is setup or not. It is set or cleared in vhost_scsi_set_endpoint() or vhost_scsi_clear_endpoint() under the vs->dev.mutex lock. However, when we check it in vhost_scsi_handle_vq(), we ignored the lock. Instead of using the vs->vs_endpoint and the vs->dev.mutex lock to indicate the status of the endpoint, we use per virtqueue vq->private_data to indicate it. In this way, we can only take the vq->mutex lock which is per queue and make the concurrent multiqueue process having less lock contention. Further, in the read side of vq->private_data, we can even do not take the lock if it is accessed in the vhost worker thread, because it is protected by "vhost rcu".

2013-04-08bonding: fix bonding_masters race condition in bond unloadingnikolay@redhat.com
While the bonding module is unloading, it is considered that after rtnl_link_unregister all bond devices are destroyed but since no synchronization mechanism exists, a new bond device can be created via bonding_masters before unregister_pernet_subsys which would lead to multiple problems (e.g. NULL pointer dereference, wrong RIP, list corruption).

2013-04-08hyperv: Fix a kernel warning from netvsc_linkstatus_callback()Haiyang Zhang
The warning about local_bh_enable inside IRQ happens when disconnecting a virtual NIC. The reason for the warning is -- netif_tx_disable() is called when the NIC is disconnected. And it's called within irq context. netif_tx_disable() calls local_bh_enable() which displays warning if in irq. The fix is to remove the unnecessary netif_tx_disable & wake_queue() in the netvsc_linkstatus_callback().

2013-04-06[SCSI] libsas: fix handling vacant phy in sas_set_ex_phy()Lukasz Dorau
If a result of the SMP discover function is PHY VACANT, the content of discover response structure (dr) is not valid. It sometimes happens that dr->attached_sas_addr can contain even SAS address of other phy. In such case an invalid phy is created, what causes NULL pointer dereference during destruction of expander's phys. So if a result of SMP function is PHY VACANT, the content of discover response structure (dr) must not be copied to phy structure. This patch fixes the following bug: BUG: unable to handle kernel NULL pointer dereference at 0000000000000030 IP: [<ffffffff811c9002>] sysfs_find_dirent+0x12/0x90 Call Trace: [<ffffffff811c95f5>] sysfs_get_dirent+0x35/0x80 [<ffffffff811cb55e>] sysfs_unmerge_group+0x1e/0xb0 [<ffffffff813329f4>] dpm_sysfs_remove+0x24/0x90 [<ffffffff8132b0f4>] device_del+0x44/0x1d0 [<ffffffffa016fc59>] sas_rphy_delete+0x9/0x20 [scsi_transport_sas] [<ffffffffa01a16f6>] sas_destruct_devices+0xe6/0x110 [libsas] [<ffffffff8107ac7c>] process_one_work+0x16c/0x350 [<ffffffff8107d84a>] worker_thread+0x17a/0x410 [<ffffffff81081b76>] kthread+0x96/0xa0 [<ffffffff81464944>] kernel_thread_helper+0x4/0x10 Signed-off-by: Lukasz Dorau <lukasz.dorau@intel.com> Signed-off-by: Pawel Baldysiak <pawel.baldysiak@intel.com> Reviewed-by: Maciej Patelczyk <maciej.patelczyk@intel.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

Commit e2eed58b4fbf ("IB/qib: change QLogic to Intel") moved a firmware file potentially breaking the ABI.

2013-04-05Revert "drivers/rtc/rtc-at91rm9200.c: use a variable for storing IMR"Johan Hovold
This reverts commit 0ef1594c017521ea89278e80fe3f80dafb17abde. This patch introduced a few races which cannot be easily fixed with a small follow-up patch. Furthermore, the SoC with the broken hardware register, which this patch intended to add support for, can only be used with device trees, which this driver currently does not support.

2013-04-05hwspinlock: fix __hwspin_lock_request error pathLi Fei
Even in failed case of pm_runtime_get_sync, the usage_count is incremented. In order to keep the usage_count with correct value and runtime power management to behave correctly, call pm_runtime_put_noidle in such case. In __hwspin_lock_request, module_put is also called before return in pm_runtime_get_sync failed case.

2013-04-05dm cache: reduce bio front_pad size in writeback modeMike Snitzer
A recent patch to fix the dm cache target's writethrough mode extended the bio's front_pad to include a 1056-byte struct dm_bio_details. Writeback mode doesn't need this, so this patch reduces the per_bio_data_size to 16 bytes in this case instead of 1096. The dm_bio_details structure was added in "dm cache: fix writes to cache device in writethrough mode" which fixed commit e2e74d617e ("dm cache: fix race in writethrough implementation"). In writeback mode we avoid allocating the writethrough-specific members of the per_bio_data structure (the dm_bio_details structure included).

2013-04-05dm cache: fix writes to cache device in writethrough modeDarrick J. Wong
The dm-cache writethrough strategy introduced by commit e2e74d617eadc15 ("dm cache: fix race in writethrough implementation") issues a bio to the origin device, remaps and then issues the bio to the cache device. This more conservative in-series approach was selected to favor correctness over performance (of the previous parallel writethrough). However, this in-series implementation that reuses the same bio to write both the origin and cache device didn't take into account that the block layer's req_bio_endio() modifies a completing bio's bi_sector and bi_size. So the new writethrough strategy needs to preserve these bio fields, and restore them before submission to the cache device, otherwise nothing gets written to the cache (because bi_size is 0). This patch adds a struct dm_bio_details field to struct per_bio_data, and uses dm_bio_record() and dm_bio_restore() to ensure the bio is restored before reissuing to the cache device. Adding such a large structure to the per_bio_data is not ideal but we can improve this later, for now correctness is the important thing. This problem initially went unnoticed because the dm-cache test-suite uses a linear DM device for the dm-cache device's origin device. Writethrough worked as expected because DM submits a *clone* of the original bio, so the original bio which was reused for the cache was never touched. Signed-off-by: Darrick J.

2013-04-05crypto: ux500 - add missing commaLinus Walleij
Commit 4f31f5b19eb0418a847b989abc9ac22af1991fe2 "PM / crypto / ux500: Use struct dev_pm_ops for power management" add a new line to the driver struct but missed to add a trailing comma, causing build errors when crypto is selected. This adds the missing comma. This was not noticed until now because the crypto block is not in the ux500 defconfig. A separate patch will be submitted to fix this.
