75426367cd drm/ioctl: Ditch DRM_UNLOCKED except for the legacy vblank ioctl 
This completes Emil's series of removing DRM_UNLOCKED from modern
drivers. It's entirely cargo-culted since we ignore it on
non-DRIVER_LEGACY drivers since:

commit ea487835e8
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Mon Sep 28 21:42:40 2015 +0200

    drm: Enforce unlocked ioctl operation for kms driver ioctls

Now justifying why we can do this for legacy drives too (and hence
close the source of all the bogus copypasting) is a bit more involved.
DRM_UNLOCKED was introduced in:

commit ed8b670409
Author: Arnd Bergmann <arnd@arndb.de>
Date:   Wed Dec 16 22:17:09 2009 +0000

    drm: convert drm_ioctl to unlocked_ioctl

As a immediate hack to keep i810 happy, which would have deadlocked
without this trickery. The old BKL is automatically dropped in
schedule(), and hence the i810 vs. mmap_sem deadlock didn't actually
cause a real deadlock. But with a mutex it would. The solution was to
annotate these as DRM_UNLOCKED and mark i810 unsafe on SMP machines.

This conversion caused a regression, because unlike the BKL a mutex
isn't dropped over schedule (that thing again), which caused a vblank
wait in one thread to block the entire desktop and all its apps. Back
then we did vblank scheduling by blocking in the client, awesome isn't
it. This was fixed quickly in (ok not so quickly, took 2 years):

commit 8f4ff2b06a
Author: Ilija Hadzic <ihadzic@research.bell-labs.com>
Date:   Mon Oct 31 17:46:18 2011 -0400

    drm: do not sleep on vblank while holding a mutex

All the other DRM_UNLOCKED annotations for all the core ioctls was
work to reach finer-grained locking for modern drivers. This took
years, and culminated in:

commit fdd5b877e9
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Sat Dec 10 22:52:54 2016 +0100

    drm: Enforce BKL-less ioctls for modern drivers

DRM_UNLOCKED was never required by any legacy drivers, except for the
vblank_wait IOCTL. Therefore we will not regress these old drivers by
going back to where we've been in 2011. For all modern drivers nothing
will change.

To make this perfectly clear, also add a comment to DRM_UNLOCKED.

v2: Don't forget about drm_ioc32.c (Michel).

e4fa8457b2 drm/prime: Align gem_prime_export with obj_funcs.export 
The idea is that gem_prime_export is deprecated in favor of
obj_funcs.export. That's much easier to do if both have matching
function signatures.

8b3026a74f drm/omapdrm: drop fb_debug_enter/leave 
This is a no-op on atomic drivers because with atomic it's simply too
complicated to get all the locking and workers and nonblocking
synchronization correct, from essentially an NMI context. Well, too
complicated = impossible. Also, omapdrm never implemented the
mode_set_base_atomic hook, so I kinda wonder why this was ever added.

Drop the hooks.

4c6d51ea2a drm/i915: Make timelines gt centric 
Our timelines are stored inside intel_gt so we can convert the interface
to take exactly that and not i915.

At the same time re-order the params to our more typical layout and
replace the backpointer to the new containing structure.

This patch handles a few of the easy ones with work requiring more
