Updated pull request after I pulled first time :)
* 'drm-intel-next' of git://anongit.freedesktop.org/git/drm-intel:
drm/i915: Pevent copying uninitialised garbage into vma->ggtt_view
Hope I'm not too late before the cutoff for the v4.11 with these patches.
Mostly an asorted set of fixes that we have discovered while playing with
the code and preparing for the next set of features.
* 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld:
drm: mali-dp: fix stride setting for multi-plane formats
drm: mali-dp: Add plane offset to the plane's physical start address register
drm: mali-dp: Check for sufficient address space
drm: mali-dp: Check hw version matches device-tree

The function is not that big, but it's also not used for anything
performance critical. Make it a normal function.
As a side effect, this apparently makes sparse smarter about what it's
doing, and gets rid of the warning:
./include/drm/drm_color_mgmt.h:53:28: warning: shift too big (4294967295) for type unsigned long
./include/drm/drm_color_mgmt.h:53:28: warning: cast truncates bits from constant value (8000000000000000 becomes 0)

The size computations done in the ioctl function use an integer.
If userspace submits a request with req->cmd_nr or req->cmd_buf_nr
set to INT_MAX, the integer computations overflow later, leading
to potential (kernel) memory corruption.
Prevent this issue by enforcing a limit on the number of submitted
commands, so that we have enough headroom later for the size
computations.
Note that this change has no impact on the currently available
users in userspace, like e.g. libdrm/exynos.
While at it, also make a comment about the size computation more
detailed.

We were trying to print an error message if we timed out here, but the
loop actually ends with "tries" set to UINT_MAX and not zero. Fix this
by changing from tries-- to --tries.
A for loop would actually be the most natural way to do this. My fix
means we only loop 99 times instead of 100 but that's probably ok.

This patch replaces specific atomic commit function
with atomic helper commit one.
For this, it removes existing atomic commit function
and relevant code specific to Exynos DRM and makes
atomic helper commit to be used instead.
Below are changes for the use of atomic helper commit:
- add atomic_commit_tail callback specific to Exynos DRM
. default implemention of atomic helper doesn't mesh well
with runtime PM so the device driver which supports runtime
PM should call drm_atomic_helper_commit_modeset_enables function
prior to drm_atomic_helper_commit_planes function call.
atomic_commit_tail callback implements this call ordering.
- allow plane commit only in case that CRTC device is enabled.
. for this, it calls atomic_helper_commit_planes function
with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.

There are a few hardware bits for each graphic layer to control main/aux
channel and clock selection, as well as the layer enabling. These bits
sit outside the layer block itself, but in VOU control glue block. We
currently set these bits up at CRTC initialization for once, and do not
support disabling the layer.
This patch creates a pair of functions zx_vou_layer_enable[disable] to
be invoked from plane hooks .atomic_update and .atomic_disable to set up
and tear down the layer. This is generic for both graphic and video
layers, so it will make the overlay plane support to be added later much
easier.

Move struct zx_plane from zx_plane.c to zx_plane.h, so that it can be

zx_layer_data completely. More importantly, those additional data used
by VOU controller to enable/disable graphic and video layers can later
be added and accessed much more easily from zx_vou driver.
While at it, we make two changes to zx_plane_init() interface:
- Encode struct device pointer in zx_plane, so that we do not need to
pass it as a parameter.
- Change return of zx_plane_init() from struct drm_plane pointer to
error code, since we can get the pointer from zx_plane in zx_vou

--------------
v4: Changes suggested by Emil, Christian
- return -ENODATA for asics with unlimited sessions
v3: changes suggested by Christian
- Add a check for UVD IP block using AMDGPU_HW_IP_UVD
query type.
- Add a check for asic_type to be less than
CHIP_POLARIS10 since starting Polaris, we support
unlimited UVD instances.
- Add kerneldoc style comment for
amdgpu_uvd_used_handles().
v2: as suggested by Christian
- Add a new query AMDGPU_INFO_NUM_HANDLES
- Create a helper function to return the number
of currently used UVD handles.
- Modify the logic to count the number of used
UVD handles since handles can be freed in
non-linear fashion.
v1:
- User might want to query the maximum number of UVD
instances supported by firmware. In addition to that,
if there are multiple applications using UVD handles
at the same time, he might also want to query the
currently used number of handles.
For this we add two variables max_handles and
used_handles inside drm_amdgpu_info_hw_ip. So now
an application (or libdrm) can use AMDGPU_INFO IOCTL
with AMDGPU_INFO_HW_IP_INFO query type to get these
values.

drm/probe-helpers: Drop locking from poll_enable

drm/probe-helper: Grab mode_config.mutex in poll_init/enable
Unfortunately the commit message of that patch fails to mention that
the new locking check was for the connector_list.
But that requirement disappeared in

drm: Convert all helpers to drm_connector_list_iter
and so we can drop this again.
This fixes a locking inversion on nouveau, where the rpm code needs to
re-enable. But in other places the rpm_get() calls are nested within
the big modeset locks.
While at it, also improve the kerneldoc for these two functions a
notch.
v2: Update the kerneldoc even more to explain that these functions
can't be called concurrently, or bad things happen (Chris).
Backmerge Linus master to get the connector locking revert.

CEA-861-F tells us:
"When transmitting any RGB colorimetry, the Source should set the
YQ-field to match the RGB Quantization Range being transmitted
(e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB,
set YQ=1) and the Sink shall ignore the YQ-field."
So let's go ahead and do that. Perhaps there are sinks that don't
ignore the YQ as they should for RGB?
I wasn't able to find similar text in CEA-861-E, so it would seem
to be a fairly "recent" addition.

HDMI 2.0 recommends that we set the Q bits in the AVI infoframe
even when the sink does not support quantization range selection (QS=0).
According to CEA-861 we can do that as long as the Q we send matches
the default quantization range for the mode.
Previously I think I had misread the spec as saying that you can't
send a non-zero Q at all when QS=0. But that's not what the spec
actually says.

Pull the logic to populate the quantization range information

Since tweaking i915_vma_compare() we allowed constructors to skip
clearing the ggtt_view believing that we didn't access the unused
members. That, as it turns out, was not entirely true. In particular,
i915_gem_fault() uses
ret = remap_io_mapping(area,
area->vm_start + (vma->ggtt_view.partial.offset << PAGE_SHIFT),
(ggtt->mappable_base + vma->node.start) >> PAGE_SHIFT,
min_t(u64, vma->size, area->vm_end - area->vm_start),
&ggtt->mappable);
i.e. the ggtt_view.partial for both normal and partial views. If we
allowed garbage into the normal vma->ggtt_view and then try userspace
tried to mmap it, we could explode in an unobvious fashion.

Use the same trick we used for i915 when we still had ums support:
Just initialize the agp support unconditionally in the driver load
function.
Unfortunately that means we need to export drm_agp_init again, but I

There were some precursor commits missing for this around connector
locking, we should probably merge Lyude's nouveau avoid the problem patch.
After going through all the trouble of splitting out parts from

struct drm_dp_mst_topology_mgr currently stores a pointer to struct dev.
Changing this to instead hold a pointer to drm_device is more useful as it
gives access to DRM structures. This also makes it consistent with other
DRM structures like drm_crtc, drm_connector etc.
