Florian Tobias Schandinat 0febd3bccf Omapdss driver changes for the 3.7 merge window.
Notable changes:
 
 * Basic writeback support for DISPC level. Writeback is not yet usable, though,
   as we need higher level code to actually expose the writeback feature to
   userspace.
 * Rewriting the omapdss output drivers. We're trying to remove the hard links
   between the omapdss and the panels, and this rewrite work moves us closer to
   that goal.
 * Cleanup and restructuring patches that have been made while working on device
   tree support for omapdss. Device tree support is still some way ahead, but
   these patches are good cleanups in themselves.
 * Basic OMAP5 DSS support for DPI and DSI outputs.
 * Workaround for the problem that GFX overlay's fifo is too small for high
   resolution scenarios, causing underflows.
 * Cleanups that remove dependencies to omap platform code.

Konstantin Khlebnikov 314e51b985 mm: kill vma flag VM_RESERVED and mm->reserved_vm counter
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:

 | effect                 | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump      | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock           | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP

This patch removes reserved_vm counter from mm_struct.  Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.

Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.

remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

Now that we correctly generate it, this hack is no longer required (and
might actually paper over a serious bug).

pageflip timestamps are sanity check in the latest version of the flip-test
in intel-gpu-tools.

Daniel Vetter 74d44445af drm/i915: call drm_handle_vblank before finish_page_flip
... since finish_page_flip needs the vblank timestamp generated
in drm_handle_vblank. Somehow all the gmch platforms get it right,
but all the pch platform irq handlers get is wrong. Hooray for copy&
pasting!

Currently this gets papered over by a gross hack in finish_page_flip.
A second patch will remove that.

Note that without this, the new timestamp sanity checks in flip_test
occasionally get tripped up, hence the cc: stable tag.

Dmitry Rogozhkin e79e0fe380 drm/i915: EBUSY status handling added to i915_gem_fault().
Subsequent threads returning EBUSY from vm_insert_pfn() was not handled
correctly. As a result concurrent access from new threads to
mmapped data caused SIGBUS.

Note that this fixes i-g-t/tests/gem_threaded_tiled_access.

    drm/i915: Try harder during dp pattern 1 link training

extra passes were made to retry the same voltage and then retry a full
clock reset. However, as coverity pointed out, we never tried the full
clock reset as we broke out of the loop early.

Linus Torvalds 612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Inki Dae 58f6aad7d9 drm/exynos: fix display power call issue.
Changelog v3:
make exynos_drm_display_power function use exynos_drm_best_encoder
function instead of connector->encoder to get a valid encoder.
connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB
request, connector->encoder is NULL so fix this issue.

Changelog v2:
remove static prefix so that exynos_drm_best_encoder function
could be called by other modules.

Changelog v1:
this patch fixes the issue that display power callback isn't called.
with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL
so display_ops->power_on() wouldn't be called so this patch makes
exynos_drm_best_encoder function to be used to get a valid encoder
of each connector.

Inki Dae bcf4cef942 drm/exynos: Disable plane when released
this patch ensures that each plane connected to encoder is disabled
when released, by adding disable callback function of encoder helper

we had faced with one issue that invalid memory is accessed by dma
once drm is released and then the dma is turned on again. actually,
in our case, page fault was incurred with iommu. the reason is that
a gem buffer accessed by the dma is also released once drm is released.

so this patch would fix this issue ensuring the dma is disabled
when released.

but when booted, the buffer count will always be 1 because pixel
