Merge tag 'topic/drm-misc-2016-02-18' of git://anongit.freedesktop.org/drm-intel into drm-next

Misc stuff all over:
- more mode_fixup removal from Carlos, there's another final pile still
  left.
- final bits of vgaswitcheroo from Lukas for apple gmux, we're still
  discussing an api cleanup patch to make it a bit more abuse-safe as a
  follow-up
- dp aux interface for userspace for tools&tests from Rafael Antognolli
- actual interface parts for dma-buf flushing for userspace mmap
- few small bits all over

- vgaswitcheroo support for apple gmux from Lukas Wunner
- checks for ->mode_fixup in non-atomic helpers from Carlos Palminha, plus
  removing dummy funcs from drivers. Carlos promised to follow up with
  more, since there's lots more silly dummy functions around.
- dma-buf patches from Tiago, except the ioctl itself (that needed a
  respin to address review from David Herrmann)
- encoder mask for atomic from Maarten
- bunch of random things all over.
