Merge branch 'for-linux-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-next 

Daniel writes:
A few intel fixes for smaller issues and one revert for an sdv hack which
we've wanted to kill anyway. Plus two drm patches included for your
convenience, both regression fixers for mine own screw-ups.

+ both fixes for stolen mem handling.

* 'for-linux-next' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: clear the stolen fb before resuming
  Revert "drm/i915: Calculate correct stolen size for GEN7+"
  drm/i915: hsw: fix link training for eDP on port-A
  Revert "drm/i915: revert eDP bpp clamping code changes"
  drm: don't check modeset locks in panic handler
  drm/i915: Fix pipe enabled mask for pipe C in WM calculations
  drm/mm: fix dump table BUG
  drm/i915: Always normalize return timeout for wait_timeout_ioctl
