The Analogix 7737 DP to HDMI converter requires reduced M and N values
when to operate correctly at HBR2. We tried to reduce the M/N values for
all devices in commit 9a86cda07af2 ("drm/i915/dp: reduce link M/N
parameters"), but that regressed some other sinks. Detect this IC by its
OUI value of 0x0022B9 via the DPCD quirk list, and only reduce the M/N
values for that.

Face the fact, there are Display Port sink and branch devices out there
in the wild that don't follow the Display Port specifications, or they
have bugs, or just otherwise require special treatment. Start a common
quirk database the drivers can query based on the DP device
identification. At least for now, we leave the workarounds for the
drivers to implement as they see fit.
For starters, add a branch device that can't handle full 24-bit main
link Mdiv and Ndiv main link attributes properly. Naturally, the
workaround of reducing main link attributes for all devices ended up in
regressions for other devices. So here we are.

Pull gcc-plugin prepwork from Kees Cook:
"Use designated initializers for mtk-vcodec, powerplay, amdgpu, and
sgi-xp. Use ERR_CAST() to avoid cross-structure cast in ocf2, ntfs,

Christoph Hellwig recommended that I send these fixes now, rather than
waiting for the v4.13 merge window. These are all initializer and cast
fixes needed for the future randstruct plugin that haven't been picked
up by the respective maintainers"

The dsi + panel is a parental relationship, so OF grpah is not needed.
Therefore, the current dsi_parse_dt function will throw an error,
because there is no linked OF graph for the case fimd + dsi + panel.
Parse the Pll burst and esc clock frequency properties in dsi_parse_dt()
and create a bridge_node only if there is an OF graph associated with dsi.

The overrun check for the size of submitted commands is off by one.
It should allow the offset plus the size to be equal to the
size of the memory object when the command stream is very tightly
constructed.

Amongst its other duties, msm_gem_new_impl adds the newly created
GEM object to the shared inactive list which may also be actively
modifiying the list during submission. All the paths to modify
the list are protected by the mutex except for the one through
msm_gem_import which can end up causing list corruption.

Somehow the helper was never retrofitted for mdp5. Which meant when
plane_state->fence was added, it could get copied into new state in
mdp5_plane_duplicate_state().
If an update to disable the plane (for example on rmfb) managed to sneak
in after an nonblock update had swapped state, but before it was
committed, we'd get a splat:

vlv_display_irq_postinstall() enables the LPE audio interrupts
regardless of whether the LPE audio irq chip has masked/unmasked
them. Also the irqchip masking/unmasking doesn't consider the state
of the display power well or the device, and hence just leads to
dmesg spew when it tries to access the hardware while it's powered
down.
If the current way works, then we don't need to do anything in the
mask/unmask hooks. If it doesn't work, well, then we'd need to properly
track whether the irqchip has masked/unmasked the interrupts when
we enable display interrupts. And the mask/unmask hooks would need
to check whether display interrupts are even enabled before frobbing
with he registers.
So let's just assume the current way works and neuter the mask/unmask
hooks. Also clean up vlv_display_irq_postinstall() a bit and stop
it from trying to unmask/enable the LPE C interrupt on VLV since it
doesn't exist.

the first pass, leading to:

v2: Make it more obvious by setting obj to NULL on the first pass and
any later pass where we need to reallocate.

During execlist_context_deferred_alloc() we presumed that the context is
uninitialised (we only just allocated the state object for it!) and
chose to optimise away the later call to engine->init_context() if
engine->init_context were NULL. This breaks with GVT's contexts that are
marked as pre-initialised to avoid us annoyingly calling
engine->init_context(). The fix is to not override ce->initialised if it
is already true.

For the aliasing ppgtt we clear the va range up to vma->size, but seem
to allocate up to vma->node.size, which is a little inconsistent given
that vma->node.size >= vma->size. Not that is really matters all that
much since we preallocate anyway, but for consistency just use
vma->size.

Due to the complex dependencies between workqueues and RCU, which
are not easily detected by lockdep, do not synchronize RCU during
shrinking.
On low-on-memory systems (mem=1G for example), the RCU sync leads
to all system workqueus freezing and unrelated lockdep splats are
displayed according to reports. GIT bisecting done by J. R.
Okajima points to the commit where RCU syncing was extended.
RCU sync gains us very little benefit in real life scenarios
where the amount of memory used by object backing storage is
dominant over the metadata under RCU, so drop it altogether.
" Yeeeaah, if core could just, go ahead and reclaim RCU
queues, that'd be great. "
- Chris Wilson, 2016 (0eafec6d3244)

We end up reading the interrupt register for HPD5, and then writing it
to HPD6 which on systems without anything using HPD5 results in
permanently disabling hotplug on one of the display outputs after the
first time we acknowledge a hotplug interrupt from the GPU.
This code is really bad. But for now, let's just fix this. I will
hopefully have a large patch series to refactor all of this soon.

Reinitializing the VM manager during suspend/resume is a very very bad
idea since all the VMs are still active and kicking.
This can lead to random VM faults after resume when new processes
become the same client ID assigned.

With LVDS we were incorrectly picking the pre-programmed mode instead of
the prefered mode provided by VBT. Make sure we pick the VBT mode if
one is provided. It is likely that the mode read-out code is still wrong
but this patch fixes the immediate problem on most machines.

I failed to properly onion-wrap the unwind code: We acquire the vblank
reference before we start with the wait-wound locking dance, hence we
must make sure we retry before we drop the reference. Oops.
v2: The vblank_put must be after the frambuffer_put (Michel). I suck at
unwrapping code that doesn't use separate labels for each stage, but
checks each pointer first ... While re-reading everything I also
realized that we must clean up the fb refcounts, and specifically
plane->old_fb before we drop the locks, either in the final unlocking,
or in the w/w retry path. Hence the correct fix is to drop the
vblank_put to the very bottom.

qxl_release_map will enter an atomic context, but since we still need to
alloc memory for BOs, we better delay that until we have everything we
need, in case we need to sleep inside the allocation. This avoids the
Sleep in atomic state below, which was reported by Mike.

Nicolai Stange reports the following oops which is caused by
dereferencing rdev->pdev before it's subsequently set by
radeon_device_init(). Fix it.
