2016-02-16bonding: don't use stale speed and duplex informationJay Vosburgh
There is presently a race condition between the bonding periodic link monitor and the updating of a slave's speed and duplex. The former occurs on a periodic basis, and the latter in response to a driver's calling of netif_carrier_on. It is possible for the periodic monitor to run between the driver call of netif_carrier_on and the receipt of the NETDEV_CHANGE event that causes bonding to update the slave's speed and duplex. This manifests most notably as a report that a slave is up and "0 Mbps full duplex" after enslavement, but in principle could report an incorrect speed and duplex after any link up event if the device comes up with a different speed or duplex. This affects the 802.3ad aggregator selection, as the speed and duplex are selection criteria. This is fixed by updating the speed and duplex in the periodic monitor, prior to using that information. This was done historically in bonding, but the call to bond_update_speed_duplex was removed in commit 876254ae2758 ("bonding: don't call update_speed_duplex() under spinlocks"), as it might sleep under lock. Later, the locking was changed to only hold RTNL, and so after commit 876254ae2758 ("bonding: don't call update_speed_duplex() under spinlocks") this call is again safe.

2016-02-16drm/vc4: Add support for YUV planes.Eric Anholt
This supports 420 and 422 subsampling with 2 or 3 planes, tested with modetest. It doesn't set up chroma subsampling position (which it appears KMS doesn't deal with yet). The LBM memory is overallocated in many cases, but apparently the docs aren't quite correct and I'll probably need to look at the hardware source to really figure it out.

2016-02-16drm/vc4: Add more display planes to each CRTC.Eric Anholt

2016-02-16drm/vc4: Make the CRTCs cooperate on allocating display lists.Eric Anholt
So far, we've only ever lit up one CRTC, so this has been fine. To extend to more displays or more planes, we need to make sure we don't run our display lists into each other. Signed-off-by: Eric Anholt <eric@anholt.net>
2016-02-16drm/vc4: Add a proper short-circut path for legacy cursor updates.Eric Anholt
Previously, on every modeset we would allocate new display list memory, recompute changed planes, write all of them to the new memory, and pointed scanout at the new list (which will latch approximately at the next line of scanout). We let drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait for a vblank after a modeset before cleaning up the old state and letting the next modeset proceed, and on legacy cursor updates we wouldn't wait. If you moved the cursor fast enough, we could potentially wrap around the display list memory area and overwrite the existing display list while it was still being scanned out, resulting in the HVS scanning out garbage or just halting. Instead of making cursor updates wait for scanout to move to the new display list area (which introduces significant cursor lag in X), we just rewrite our current display list.

2016-02-16writeback: keep superblock pinned during cgroup writeback association switchesTejun Heo
If cgroup writeback is in use, an inode is associated with a cgroup for writeback. If the inode's main dirtier changes to another cgroup, the association gets updated asynchronously. Nothing was pinning the superblock while such switches are in progress and superblock could go away while async switching is pending or in progress leading to crashes like the following. kernel BUG at fs/jbd2/transaction.c:319! invalid opcode: 0000 [#1] SMP DEBUG_PAGEALLOC CPU: 1 PID: 29158 Comm: kworker/1:10 Not tainted 4.5.0-rc3 #51 Hardware name: Google Google, BIOS Google 01/01/2011 Workqueue: events inode_switch_wbs_work_fn task: ffff880213dbbd40 ti: ffff880209264000 task.ti: ffff880209264000 RIP: 0010:[<ffffffff803e6922>] [<ffffffff803e6922>] start_this_handle+0x382/0x3e0 RSP: 0018:ffff880209267c30 EFLAGS: 00010202 ...

2016-02-16af_unix: Guard against other == sk in unix_dgram_sendmsgRainer Weikusat
The unix_dgram_sendmsg routine use the following test if (unlikely(unix_peer(other) != sk && unix_recvq_full(other))) { to determine if sk and other are in an n:1 association (either established via connect or by using sendto to send messages to an unrelated socket identified by address). This isn't correct as the specified address could have been bound to the sending socket itself or because this socket could have been connected to itself by the time of the unix_peer_get but disconnected before the unix_state_lock(other). In both cases, the if-block would be entered despite other == sk which might either block the sender unintentionally or lead to trying to unlock the same spin lock twice for a non-blocking send. Add a other != sk check to guard against this.

The OMAP one is a bit worrying since it seems to be triggered by some changes in the runtime PM core code and I suspect there's other drivers across that are going to be using the same pattern outside of OMAP but nothing seems to be coming up in the testing people are doing" * tag 'spi-fix-v4.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: omap2-mcspi: Fix PM regression with deferred probe for pm_runtime_reinit spi: bcm2835aux: fix bitmask defines spi: atmel: fix gpio chip-select in case of non-DT platform spi/fsl-espi: Correct the maximum transaction length spi: imx: fix spi resource leak with dma transfer spi: fix counting in spi-loopback-test code
