Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
nonblocking ioctl and async flip (= not vblank synced), from Maarten.
Needs to be regened with newer drivers, but probably only after -rc1 to
catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.
Keeps the udl hack, and qxl is tested by Gerd.

Finally all the core gem and a lot of drivers are entirely free of
dev->struct_mutex depencies, and we can start to have an entirely
lockless unref path.
To make sure that no one who touches the core code accidentally breaks
existing drivers which still require dev->struct_mutex I've made the
might_lock check unconditional.
While at it de-inline the ref/unref functions, they've become a bit
too big.
v2: Make it not leak like a sieve.
v3: Review from Lucas:
- drop != NULL in pointer checks.
- fixup copypasted kerneldoc to actually match the functions.
v4:
Add __drm_gem_object_unreference as a fastpath helper for drivers who
abolished dev->struct_mutex, requested by Chris.
v5: Fix silly mistake in drm_gem_object_unreference_unlocked caught by
intel-gfx CI - I checked for gem_free_object instead of
gem_free_object_unlocked ...

Here are a few amdkfd patches for 4.7, all of them fixes according to
the Coccinelle tool.
* tag 'drm-amdkfd-next-2016-05-04' of git://people.freedesktop.org/~gabbayo/linux:
amdkfd: Trim unnescessary intermediate err var in kfd_chardev.c
amdkfd: Trim off unnescessary semicolon from kfd_packet_manager.c
amdkfd: Use the canonical form in branch predicates
Here are some little fixes for rockchip drm, looks good for me, and seems there is no doubt on them, So I'd like you can land them.
* 'drm-rockchip-next-fixes-05-03' of https://github.com/markyzq/kernel-drm-rockchip:
drm/rockchip: vop: Initialize vskiplines to zero
drm/rockchip: vop: fix iommu crash with async atomic
drm/rockchip: support non-iommu buffer path
drm/rockchip: get rid of rockchip_drm_crtc_mode_config
drm/rockchip: inno_hdmi: fix an error code
drm/rockchip: don't leak iommu mapping
drm/rockchip: remove redundant statement
Summary:
- Support for pipeline clock between KMS drivers.
. Exynos SoC is required to control clocks across KMS drivers
according to Exynos SoC version. So this patch refactos
some relevant codes and provides generic solution for it.
- Add Exynos5433 SoC support to HDMI parts - HDMI and DECON-TV.
- Add HW trigger mode support to CRTC drivers.
. In case of using i80 Panel, some Exynos SoC supports HW trigger
mode so this patch makes trigger mode - HW or SW trigger - to be
set according to SoC version properly.
- And some cleanups and regression fixups.

This pull request brings in DPI panel support, gamma ramp support, and
render nodes for vc4.
* tag 'drm-vc4-next-2016-05-02' of https://github.com/anholt/linux:

- prep work for struct_mutex-less gem_free_object
- more invasive/tricky mst fixes from Lyude for broken hw. I discussed
this with Ville/Jani and we all agreed more soaking in -next would be
real good this late in the -rc cycle. They're cc: stable too to make
sure they're not getting lost. Feel free to cherry-pick those four if
you disagree.
- few small things all over

Pretty much all of these hasn't seen any action singe 2008 at the very
least. Barring the occasional buildfix and DRM-wide refactoring of
course.
Note: some distributions have stopped shipping their userspace
counterparts for a while. Although some still do.
