Daniel writes:
A few fixes, nothing shocking:
- More Haswell pci ids. Includes a pile of marketing spare ids (which
  despite the spare moniker show up all over the place).
- Fix a regression in handling modeset failures, resulting in black
  screens on 3 pipe setups when we've run out of pch plls (Chris).
- Fix up the setcrtc semantics to unconditionally enable the outputs.
  Juding from git digging that has (kinda) always been the case and neatly
  fixes a few long-standing (i.e. forever) bug reports (Imre).
- jiffies_timeout + 1 patches from Imre. They partially fix spurious
  wait_event failures in the interrupt-driven dp aux/i2c code. The other
  part is a core patch for the wait_event macros going in through -mm. A
  few patches more than strictly required since Imre is pushing for a
  general solution in 3.11.

* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: avoid premature DP AUX timeouts
  drm/i915: avoid premature timeouts in __wait_seqno()
  drm/i915: use msecs_to_jiffies_timeout instead of open coding the same
  drm/i915: add msecs_to_jiffies_timeout to guarantee minimum duration
  drm/i915: force full modeset if the connector is in DPMS OFF mode
  drm/i915: Propagate errors back from fb set-base
  drm/i915: Adding more reserved PCI IDs for Haswell.
