into drm-fixes Fix for nasty crash on mdp4 in disable path, fix for dma-buf export, smb leak on mdp5 which could result in intermittent modeset fails, and don't let interrupted system call disturb atomic commit once we are past the point of no return. * 'msm-fixes-4.2' of git://people.freedesktop.org/~robclark/linux: drm/msm/mdp5: release SMB (shared memory blocks) in various cases drm/msm: change to uninterruptible wait in atomic commit drm/msm: mdp4: Fix drm_framebuffer dereference crash drm/msm: fix msm_gem_prime_get_sg_table()
2015-07-29drm/msm/mdp5: release SMB (shared memory blocks) in various casesWentao Xu
Release all blocks after the pipe is disabled, even when vsync didn't happen in some error cases. Allow requesting SMB multiple times before configuring to hardware, by releasing blocks not programmed to hardware yet for shrinking case. This fixes a potential leak of shared memory pool blocks.

git://anongit.freedesktop.org/drm-intel into drm-fixes Regression fix for systemd getting confused about unknown connector state after resume. Just stop setting the state to unknown, turned out to be a silly idea anyway. What drivers imo really should do (and i915 still does that) is forcing a full reprobe on resume to make sure connector changes while suspended are caught. Most drivers seem to get this wrong. Otoh it took us years to get fixes merged where some probe races resulted in eating uevents, I guess userspace expectations for reliable hpd are just really low :( * tag 'topic/drm-fixes-2015-07-23' of git://anongit.freedesktop.org/drm-intel: drm: Stop resetting connector state to unknown

2015-07-22drm: Stop resetting connector state to unknownDaniel Vetter
It's causing piles of issues since we've stopped forcing full detect cycles in the sysfs interfaces with commit c484f02d0f02fbbfc6decc945a69aae011041a27 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Mar 6 12:36:42 2015 +0000 drm: Lighten sysfs connector 'status' The original justification for this was that the hpd handlers could use the unknown state as a hint to force a full detection. But current i915 code isn't doing that any more, and no one else really uses reset on resume. So instead just keep the old state around.

2015-07-21drm/i915: Use two 32bit reads for select 64bit REG_READ ioctlsChris Wilson
Since the hardware sometimes mysteriously totally flummoxes the 64bit read of a 64bit register when read using a single instruction, split the read into two instructions. Since the read here is of automatically incrementing timestamp counters, we also have to be very careful in order to make sure that it does not increment between the two instructions. However, since userspace tried to workaround this issue and so enshrined this ABI for a broken hardware read and in the process neglected that the read only fails in some environments, we have to introduce a new uABI flag for userspace to request the 2x32 bit accurate read of the timestamp. v2: Fix alignment check and include details of the workaround for userspace.
