2016-08-25drm/i915: Move CRTC updating in atomic_commit into it's own hookLyude
Since we have to write ddb allocations at the same time as we do other plane updates, we're going to need to be able to control the order in which we execute modesets on each pipe. The easiest way to do this is to just factor this section of intel_atomic_commit_tail() (intel_atomic_commit() for stable branches) into it's own function, and add an appropriate display function hook for it. Based off of Matt Rope's suggestions Changes since v1: - Drop pipe_config->base.active check in intel_update_crtcs() since we check that before calling the function Signed-off-by: Lyude <cpaul@redhat.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> [omitting CC for stable, since this patch will need to be changed for such backports first] Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Radhakrishna Sripada <radhakrishna.sripada@intel.com> Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Lyude <cpaul@redhat.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1471961565-28540-1-git-send-email-cpaul@redhat.com

Commit e6047149db ("dm: use bio op accessors") switched DM over to using bio_set_op_attrs() but didn't take care to initialize lc->io_req.bi_op_flags in dm-log.c:rw_header(). This caused rw_header()'s call to dm_io() to make bio->bi_op_flags be uninitialized in dm-io.c:do_region(), which ultimately resulted in a SCSI BUG() in sd_init_command(). Also, adjust rw_header() and its callers to use REQ_OP_{READ|WRITE}.

We don't have code to handle any of the noc clocks in rk3399 and they're all just listed as critical clocks. Let's do the same for aclk_emmc_noc. Without this clock being marked as critical we have problems around suspend/resume after commit 20c389e656a8 ("clk: rockchip: fix incorrect aclk_emmc source gate bits on rk3399"). Before that change we were presumably not actually gating any of these clocks because we were setting the wrong gate.

2016-08-24blk-mq: improve warning for running a queue on the wrong CPUJens Axboe
__blk_mq_run_hw_queue() currently warns if we are running the queue on a CPU that isn't set in its mask. However, this can happen if a CPU is being offlined, and the workqueue handling will place the work on CPU0 instead. Improve the warning so that it only triggers if the batch cpu in the hardware queue is currently online. If it triggers for that case, then it's indicative of a flow problem in blk-mq, so we want to retain it for that case. Signed-off-by: Jens Axboe <axboe@fb.com>
2016-08-24blk-mq: don't overwrite rq->mq_ctxJens Axboe
We do this in a few places, if the CPU is offline. This isn't allowed, though, since on multi queue hardware, we can't just move a request from one software queue to another, if they map to different hardware queues. The request and tag isn't valid on another hardware queue. This can happen if plugging races with CPU offlining. But it does no harm, since it can only happen in the window where we are currently busy freezing the queue and flushing IO, in preparation for redoing the software <-> hardware queue mappings.

2016-08-24IB/srpt: Update sport->port_guid with each port refreshDoug Ledford
If port_guid is set with the default subnet_prefix, then we get a change event and run a port refresh, we don't update the port_guid. As a result, attempts to create a target device that uses the new subnet_prefix in the wwn will fail to find a match and be rejected by the ib_srpt driver. This makes it impossible to configure a port if it was initialized with a default subnet_prefix and later changed to any non-default subnet-prefix. Updating the port refresh task to always update the wwn based upon the current subnext_prefix solves this problem.

2016-08-24raid5: fix memory leak of bio integrity dataShaohua Li
Yi reported a memory leak of raid5 with DIF/DIX enabled disks. raid5 doesn't alloc/free bio, instead it reuses bios. There are two issues in current code: 1. the code calls bio_init (from init_stripe->raid5_build_block->bio_init) then bio_reset (ops_run_io). The bio is reused, so likely there is integrity data attached. bio_init will clear a pointer to integrity data and makes bio_reset can't release the data 2. bio_reset is called before dispatching bio. After bio is finished, it's possible we don't free bio's integrity data (eg, we don't call bio_reset again) Both issues will cause memory leak. The patch moves bio_init to stripe creation and bio_reset to bio end io. This will fix the two issues. Reported-by: Yi Zhang <yizhan@redhat.com> Signed-off-by: Shaohua Li <shli@fb.com>

2016-08-24mlxsw: spectrum: Add missing flood to router portIdo Schimmel
In case we have a layer 3 interface on top of a bridge (VLAN / FID RIF), then we should flood the following packet types to the router: * Broadcast: If DIP is the broadcast address of the interface, then we need to be able to get it to CPU by trapping it following route lookup. * Reserved IP multicast (224.0.0.X): Some control packets (e.g. OSPF) use this range and are trapped in the router block.

2016-08-24fuse: direct-io: don't dirty ITER_BVEC pagesMiklos Szeredi
When reading from a loop device backed by a fuse file it deadlocks on lock_page(). This is because the page is already locked by the read() operation done on the loop device. In this case we don't want to either lock the page or dirty it. So do what fs/direct-io.c does: only dirty the page for ITER_IOVEC vectors.
