Merge tag 'drm-intel-fixes-2013-12-02' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

Just flushing out my pile of bugfixes, most of them for regressions/cc:
stable. Nothing really serious going on.

For outstanding issues we still have the S4 fun due to the hsw S4
duct-tape pending (seems like I need to switch into angry maintainer mode
on that one). And there's the mode merging revert to make my g33 work
again still pending for drm core. For that one I don't have any more clue
(and it looks like no one else has a good idea either). And apparently the
locking WARN fix in here also needs to be replicated for boot, still
confirming that one though.

* tag 'drm-intel-fixes-2013-12-02' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: Pin pages whilst allocating for dma-buf vmap()
  drm/i915: MI_PREDICATE_RESULT_2 is HSW only
  drm/i915: Make the DERRMR SRM target global GTT
  drm/i915: use the correct force_wake function at the PC8 code
  drm/i915: Fix pipe CSC post offset calculation
  drm/i915: Simplify DP vs. eDP detection
  drm/i915: Check VBT for eDP ports on VLV
  drm/i915: use crtc_htotal in watermark calculations to match fastboot v2
  drm/i915: Pin relocations for the duration of constructing the execbuffer
  drm/i915: take mode config lock around crtc disable at suspend
  drm/i915: Prefer setting PTE cache age to 3
  drm/i915/ddi: set sink to power down mode on dp disable
