Previously with commit a9c1f90c8e
("drm/i915: Don't mask EI UP interrupt on IVB|SNB") certain,
seemingly unrelated bit (GEN6_PM_RP_UP_EI_EXPIRED) was needed
to be unmasked for IVB and SNB in order to prevent system hang
with chained batchbuffers.
Our CI was seeing incomplete results with tests that used
chained batches and it was found out that HSW needs to have this
same bit unmasked to reliably survive chained batches.
Always unmask GEN6_PM_RP_UP_EI_EXPIRED on Haswell to
prevent system hang with batch chaining.

Apparently some DP sinks are a little nuts and cause HPD to drop
intermittently during modesets. This happens eg. on an ASUS PB287Q.
In oder to recover from this we can't really use the previous
connector status to determine if the link needs retraining, so let's
just ignore that piece of information and do the retrain
unconditionally. We do of course still check whether the link is
supposed to be running or not.
To actually get read out the EDID and update things properly we
also need to nuke the goto out added by commit 7d23e3c37b
("drm/i915: Cleaning up intel_dp_hpd_pulse"). I'm actually not sure
why that was there. Perhaps to avoid an EDID read if the connector
status didn't appear to change, but that sort of thing is quite racy
and would have failed anyway if we failed to keep up with the
hotplugs (if we missed the HPD down in between two HPD ups). And
now that we take this codepath unconditionally we definitely need
to drop the goto as otherwise we would never do the EDID read.
v2: Drop the goto that made us skip EDID reads entirely. Doh!
v3: Rebase due to locking changes

Many sightings report the greater prevalence of allocation failures.
This is all due to the incorrect use of mapping_gfp_constraint(), so
remove it in favour of just querying the mapping_gfp_mask() which are
the exact gfp_t we wanted in the first place.
We still do expect a higher chance of reporting ENOMEM, as that is the
intention of using __GFP_NORETRY -- to fail rather than oom after having
reclaimed from our bo caches, and having done a direct|kswapd reclaim
pass.

If the engine is continually completing nops, we can saturate the
signaler and keep it working indefinitely. This angers the NMI watchdog!
A good example is to disable semaphores on snb and run igt/gem_exec_nop -
the parallel, multi-engine workloads are more than sufficient to hog the
CPU, preventing the system from even processing ICMP echo replies.
v2: Tvrtko dug into cond_resched() on x86 and found that it only
depended upon preempt_count and not tif_need_resched() - which means
that we would always call schedule() at that point.

If the signal to park arrives before we sleep, then we need to check
kthread_should_park() before sleeping to avoid missing the signal.
Otherwise, if the signal arrives whilst we are processing completed
requests, we will reset the current->state back to TASK_INTERRUPTIBLE
and so miss the wakeup.

When downscaling, mclk needs to be sufficiently higher than pxlclk in
order to be able to fetch the higher-resolution data and produce output
pixels. When not scaling, or when upscaling, mclk can be equal to
pxlclk. Since the driver doesn't control mclk, just ensure that the
requirement is satisfied with the current clock rate.

Add gamma via the DRM GAMMA_LUT/GAMMA_LUT_SIZE CRTC
properties. The expected LUT size is 4096 in order
to produce as accurate a set of segments as possible.
This version uses only the green channel's gamma curve
to set the hardware curve on DP550/650. For the sake of
simplicity, it uses the same table of coefficients for

Change "S_IRUSR | S_IWUSR" to "0600", it's easier to parse mentally.
This change should be part of commit 50f837371d ("drm/vmwgfx: Revert
"drm/vmwgfx: Replace numeric parameter like 0444 with macro""), but the
patch was truncated somewhere in the patch route, so add the missing
change. Extract from the original commit message:

Date: Thu Mar 23 14:54:48 2017 -0700
drm/vmwgfx: Revert "drm/vmwgfx: Replace numeric parameter like 0444
with macro"
This reverts commit 2d8e60e8b0 ("drm/vmwgfx: Replace numeric
parameter like 0444 with macro")
The commit belongs to the series of 1285 patches sent to LKML on
2016-08-02, it changes the representation of file permissions from
the octal value "0600" to "S_IRUSR | S_IWUSR".
The general consensus was that the changes does not increase
readability, quite the opposite; 0600 is easier to parse mentally
than S_IRUSR | S_IWUSR.

- Rename dma_buf_ops->kmap_* to avoid naming collision (Logan)
Driver changes:
- Fix UHD displays on stih407 (Vincent)
- Fix uninitialized var return in atmel-hlcdc (Dan)

dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro
drm: atmel-hlcdc: Uninitialized return in atmel_hlcdc_create_outputs()
drm/sti: fix GDP size to support up to UHD resolution
MAINTAINERS: add drm/sti driver into drm-misc
Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.
I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.
Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.
To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)
