2014-05-16drm/i915: Only unpin the default ctx object if it existsChris Wilson
Since commit 691e6415c891b8b2b082a120b896b443531c4d45 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Apr 9 09:07:36 2014 +0100 drm/i915: Always use kref tracking for all contexts. we have contexts everywhere, and so we must be careful to distinguish fake contexts, which do not have an associated bo, and real ones, which do. In particular, we now need to be careful not to dereference NULL pointers. This is one such example, as the commit highlighted above failed to move the unpinning of the default ctx object into the real-context-only branch.

2014-05-16net: phy: resume phydev when going to RESUMINGZhangfei Gao
With commit be9dad1f9f26604fb ("net: phy: suspend phydev when going to HALTED"), an unused PHY device will be put in a low-power mode using BMCR_PDOWN. Some Ethernet drivers might be calling phy_start() and phy_stop() from ndo_open and ndo_close() respectively, while calling phy_connect() and phy_disconnect() from probe and remove. In such a case, the PHY will be powered down during the phy_stop() call, but will fail to be powered up in phy_start(). This patch fixes this scenario.

2014-05-16IB/mlx4: Invoke UPDATE_QP for proxy QP1 on MAC changesMatan Barak
When we receive a netdev event indicating a netdev change and/or a netdev address change, we must change the MAC index used by the proxy QP1 (in the QP context), otherwise RoCE CM packets sent by the VF will not carry the same source MAC address as the non-CM packets. We use the UPDATE_QP command to perform this change. In order to avoid modifying a QP context based on netdev event, while the driver attempts to destroy this QP (e.g either the mlx4_ib or ib_mad modules are unloaded), we use mutex locking in both flows. Since the relevant mlx4 proxy GSI QP is created indirectly by the mad module when they create their GSI QP, the mlx4 didn't need to keep track on that QP prior to this change. Now, when QP modifications are needed to this QP from within the driver, we added refernece to it.
