drm/amd/display: Use new DRM API where possible

To conform to DRM's new API, we should not be accessing a DRM object's
internal state directly. Rather, the DRM for_each_old/new_* iterators,
and drm_atomic_get_old/new_* interface should be used.

This is an ongoing process. For now, update the DRM-facing atomic

drm/amd/display: Use DRM new-style object iterators.

Use the correct for_each_new/old_* iterators instead of for_each_*

The following functions were considered:

amdgpu_dm_find_first_crtc_matching_connector: use for_each_new
    - Old from_state_var flag was always choosing the new state

amdgpu_dm_display_resume: use for_each_new
    - drm_atomic_helper_duplicate_state is called during suspend to
      cache the state
    - It sets 'state' within the state triplet to 'new_state'

amdgpu_dm_commit_planes: use for_each_old
    - Called after the state was swapped (via atomic commit tail)

amdgpu_dm_atomic_commit: use for_each_new

    - Called before the state is swapped

v3: Say "functions considered" instead of "affected functions". The

Merge branch 'drm-next-4.15-dc' of git://people.freedesktop.org/~agd5f/linux into drm-next

Initial pull request for DC support.  We've completed a substantial amount of
the cleanup and restructuring in our TODO.  There are a few additional
cleanups that we are continuing to work on, but I don't think there are any
showstoppers remaining. We've tried to maintain most of the history for bisect
purposes.  Harry made sure all the commits build.  We've enabled DC for vega10
and Raven.  Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1),
but are not enabled by default at this point until we get further testing
upstream.

This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga,
Fiji), DCE11 (CZ, ST, Polaris), DCE12 (vega10), and DCN1 (RV) including
HDMI and DP audio, DP MST, and many other advanced display features.

Latest cleanups for DC from you and Harry.  Note that there is some
flickering on some older asics with this branch due to a regression in powerplay
that has already been fixed and will be included in my next non-DC pull request
next week.

drm/amd/sched: fix deadlock caused by unsignaled fences of deleted jobs

Highly concurrent Piglit runs can trigger a race condition where a pending
SDMA job on a buffer object is never executed because the corresponding
process is killed (perhaps due to a crash). Since the job's fences were
never signaled, the buffer object was effectively leaked. Worse, the
buffer was stuck wherever it happened to be at the time, possibly in VRAM.

The symptom was user space processes stuck in interruptible waits with
kernel stacks like:

MAINTAINERS: Add dri-devel as a mailing list for anything fbdev

fbdev is in maintenance only, except that it's still used by drm
through the drm fbdev emulation, to be able to use fbcon. And people
might want to sometimes extend fbcon to enable new features for drm
drivers, e.g. Hans' panel orientation work.

The problem is that when those patches only touch fbdev code they'll
never show up on drm developer's radar, which means we end up with
designs that don't really fit whell into the full stack. That happened
a bit with the panel orientation work, where an fbcon patch made it
into 4.14, implementing a design that won't really work on the drm
side. Which means we now have to redo things, and on top coordinate 2
subsystem trees.

Since fbdev is super low-volume we can prevent this in the future by
simply adding the dri-devel mailing list to the fbdev subsystem.

Merge branch 'timers-urgent-for-linus' of git://git./linux/kernel/git/tip/tip

Pull timer fixes from Thomas Gleixner:
 "This adds a new timer wheel function which is required for the
  conversion of the timer callback function from the 'unsigned long
  data' argument to 'struct timer_list *timer'. This conversion has two
  benefits:

   1) It makes struct timer_list smaller

   2) Many callers hand in a pointer to the timer or to the structure
      containing the timer, which happens via type casting both at setup
      and in the callback. This change gets rid of the typecasts.

  Once the conversion is complete, which is planned for 4.15, the old
  setup function and the intermediate typecast in the new setup function
  go away along with the data field in struct timer_list.

  Merging this now into mainline allows a smooth queueing of the actual
  conversion in the affected maintainer trees without creating
  dependencies"
