4f2fc25c0f drm/nouveau/fifo/gk104-: poll for runlist update completion
Newer HW doesn't appear to send this event, which will cause long delays
in runlist updates if they don't complete immediately.

RM doesn't use these events anywhere, and an NVGPU commit message notes
that polling is the preferred method even on HW that supports the event.

a7cf01809b drm/nouveau/fifo/gk104-: require explicit runlist selection for channel allocation
We didn't used to be aware that runlist/engine IDs weren't the same thing,
or that there was such variability in configuration between GPUs.

By exposing this information to a client, and giving it explicit control
of which runlist it's allocating a channel on, we're able to make better
choices.

The immediate effect of this is that on GPUs where CE0 is the "GRCE", we
will now be allocating a copy engine running asynchronously to GR for BO
migrations - as intended.

7bf5b70bef drm/nouveau/secboot: remove VLA usage
In preparation to enabling -Wvla, remove VLA. In this particular
case directly use macro NVKM_MSGQUEUE_CMDLINE_SIZE instead of local
variable cmdline_size. Also, remove cmdline_size as it is not
actually useful anymore.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
or a security flaw. Also, in general, as code evolves it is easy to
lose track of how big a VLA can get. Thus, we can end up having runtime
failures that are hard to debug.

Also, fixed as part of the directive to remove all VLAs from
the kernel: https://lkml.org/lkml/2018/3/7/621

drivers/gpu/drm/nouveau/nvif/vmm.c:40:5: note: 'stack' declared here

This makes the buffer large enough so it should serve the purpose
that the author presumably had in mind. Alternatively we could
just get rid of it completely and simplify the code at the cost
of always doing the kmalloc (as we do in the current version).

Commit 75a07f399c ("drm: rcar-du: Zero-out sg_tables when duplicating

rcar_du_vsp_plane_state that got removed in commit 301a9b8d54
("drm/rcar-du: Convert to the new generic alpha property"). The issue
stems from the merge of the two commits through separate branches and
breaks compilation of the driver. Fix it.

dd856d924b drm: rcar-du: Fix rcar_du_of_init() stub
The rcar_du_of_init() function is supposed to be defined as a stub when
CONFIG_DRM_RCAR_LVDS is disabled as the rcar_du_of.c file isn't compiled
in that case. However, a bug in the configuration option check makes it
a stub when CONFIG_DRM_RCAR_LVDS=m as well, which prevents legacy DTs
from being fixed at boot time. Fix the configuration option check by
using IS_ENABLED.

a2a330ad66 drm/amd/display: remove need of modeset flag for overlay planes (V2)
This patch is in continuation to the
"843e3c7 drm/amd/display: defer modeset check in dm_update_planes_state"
where we started to eliminate the dependency on
DRM_MODE_ATOMIC_ALLOW_MODESET to be set by the user space,
which as such is not mandatory.

After deferring, this patch eliminates the dependency on the flag
for overlay planes.

This has to be done in stages as its a pretty complex and requires thorough
testing before we free primary planes as well from dependency on modeset
flag.

V2: Simplified the plane type check.

00862edba1 drm/ttm: Use GFP_TRANSHUGE_LIGHT for allocating huge pages
GFP_TRANSHUGE tries very hard to allocate huge pages, which can result
in long delays with high memory pressure. I have observed firefox
freezing for up to around a minute due to this while restic was taking
a full system backup.

Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT |
__GFP_NORETRY instead, in order to fail quickly when there are no huge
pages available.

Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed
up in the background if necessary.

With these changes, I'm no longer seeing freezes during a restic backup.
