2014-06-02drm/dp-helper: Deprecate old i2c-over-dp_aux heleprsDaniel Vetter
Only gma500 is still using this, once that's converted we can kill all this code. If that conversion doesn't happen soonish I think we should just move this helper code into the gma500 driver itself to avoid abuse from new drivers.

2014-06-02hpsa: fix event filtering to prevent excessive rescans with old firmwareStephen M. Cameron
CTLR_STATE_CHANGE_EVENT and CTLR_STATE_CHANGE_EVENT_REDUNDANT_CNTRL do not require rescans to be initiated. Current firmware filters out these events already, but some out of date firmware doesn't, so the driver needs to filter them out too. Without this change and with out of date firmware you may see the driver spending a lot of time scanning devices unnecessarily on some Smart Arrays. Signed-off-by: Stephen M.

This patch makes sure that exynos drm framework handles deferred probe case correctly. Sub drivers could be probed before resources, clock, regulator, phy or panel, are ready for them so we should make sure that exynos drm core waits until all resources are ready and sub drivers are probed correctly. Chagelog v2: - Make sure that exynos drm core tries to bind sub drivers only in case that they have a pair: crtc and encoder/connector components should be a pair. - Remove unnecessary patch: drm/exynos: mipi-dsi: consider panel driver-deferred probe - Return error type correctly.

2014-06-01net/mlx4_en: Use affinity hintYuval Atias
The “affinity hint” mechanism is used by the user space daemon, irqbalancer, to indicate a preferred CPU mask for irqs. Irqbalancer can use this hint to balance the irqs between the cpus indicated by the mask. We wish the HCA to preferentially map the IRQs it uses to numa cores close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that sets the affinity hint according the following policy: First it maps IRQs to “close” numa cores. If these are exhausted, the remaining IRQs are mapped to “far” numa cores. Signed-off-by: Yuval Atias <yuvala@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.
