drm/i915/cmd_parser: conversion to struct drm_device logging macros.
Manually convert printk based drm logging macros to the struct
drm_device based logging macros in i915/i915_cmd_parser.c.
This also involves extracting the drm_i915_private device from various
intel types for use in the macros.
Instances of the DRM_DEBUG macro are not converted due to the lack of a
similar struct drm_device based logging macro.

drm/i915/vlv_dsi: conversion to drm_device based logging macros.
Converts the printk based logging macros to the struct drm_device based
logging macros in i915/display/vlv_dsi.c.
This was done using the following coccinelle script that transforms
based on the existence of a drm_i915_private device pointer.

drm/i915/gt: Warn about the hidden i915_vma_pin in timeline_get_seqno
On seqno rollover, we need to allocate ourselves a new cacheline. This
might incur grabbing a new page and pinning it into the GGTT, with some
rather unfortunate lockdep implications.
To avoid a mutex, and more specifically pinning in the GGTT from inside
the kernel context being used to flush the GGTT in emergencies, we will
likely need to lift the next-cacheline allocation to a pre-reservation.

forcefully by resetting the engine if it is active. If we are unable to

drm/i915: Move linetime wms into the crtc state
The linetime watermarks really have very little in common with the
plane watermarks. It looks to be cleaner to simply track them in
the crtc_state and program them from the normal modeset/fastset
paths.
The only dark cloud comes from the fact that the register is
still supposedly single buffered. So in theory it might still
need some form of two stage programming. Note that even though
HSW/BDWhave two stage programming we never computed any special
intermediate values for the linetime watermarks, and on SKL+
we don't even have the two stage stuff plugged in since everything
else is double buffered. So let's assume it's all fine and
continue doing what we've been doing.
Actually on HSW/BDW the value should not even change without
a full modeset since it doesn't account for pfit downscaling.
Thus only fastboot might be affected. But on SKL+ the pfit
scaling factor is take into consideration so the value may
change during any fastset.
As a bonus we'll plug this thing into the state
checker/dump now.
v2: Rebase due to bigjoiner prep
v2: Only compute ips linetime for IPS capable pipes.
Bspec says the register values is ignored for other
pipes, but in fact it can't even be written so the
state checker becomes unhappy if we don't compute
it as zero.

drm/i915: Use the async worker to avoid reclaim tainting the ggtt->mutex
On Braswell and Broxton (also known as Valleyview and Apollolake), we
need to serialise updates of the GGTT using the big stop_machine()
hammer. This has the side effect of appearing to lockdep as a possible
reclaim (since it uses the cpuhp mutex and that is tainted by per-cpu
allocations). However, we want to use vm->mutex (including ggtt->mutex)
from within the shrinker and so must avoid such possible taints. For this
purpose, we introduced the asynchronous vma binding and we can apply it
to the PIN_GLOBAL so long as take care to add the necessary waits for

drm/i915/dp: use intel_de_*() functions for register access
The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().
Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().
No functional changes.
