Some archs defconfigs have CONFIG_FRAME_WARN set to 1024, which lead to this
warning:
drivers/gpu/drm/nouveau/core/engine/graph/ctxnv40.c: warning: the frame size
of 1184 bytes is larger than 1024 bytes

Triggers PIBUS interrupts due to register not existing anymore, and as
a result HUB_SET_CHAN times out.
After this commit, our fuc loads and can accelerate at least fbcon, X,
glxgears and OA on NVE4. NVE7 not tested as of yet.

Currently identical except the available chipset register lists. This will
*not* currently work and is disabled by default because of this.
May get merged again later, remains to be seen what further changes will be
required.

Future code will use the object class rather than chipset checks in order to
identify available channel features.

This value will match something that's easily available from the engine IRQ
handlers, and used to lookup the relevant context.
Since the changes in how this is done on each generation match when the
major PFIFO changes happened, fifo is responsible for calculating the
correct value to avoid duplicating the same code among many engine modules.

This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination. It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.
Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.

- fix find/replace bug in license header
v3: Ben Skeggs <bskeggs@redhat.com>
- bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and
left no space for kernel's requirements during GEM pushbuf submission.
- fix duplicate assignments noticed by clang
v4: Marcin Slusarz <marcin.slusarz@gmail.com>
- add sparse annotations to nv04_fifo_pause/nv04_fifo_start
- use ioread32_native/iowrite32_native for fifo control registers
v5: Ben Skeggs <bskeggs@redhat.com>
- rebase on v3.6-rc4, modified to keep copy engine fix intact
- nv10/fence: unmap fence bo before destroying
- fixed fermi regression when using nvidia gr fuc
- fixed typo in supported dma_mask checking

This is all very much a policy thing, and hence will not belong in SW
after the rework.
engsw now only handles receiving the event to say "can flip now" and makes
a callback to perform the actual work.

There's a *lot* of code in here, and it's all going to use the PGRAPH priv
pointer rather than drm_device after the engine rework. This is handling
all the rename-only parts of the change.

Having GPUOBJ and VM intertwined like this makes it *really* hard to
continue porting to the new driver architecture, split it out in
favour of requiring explit maps be the caller.
It's more flexible and obvious this way anyway...

These currently just call the existing ones in nouveau_drv.c, but will be
extended in upcoming commits. This needed to be separated from the current
code as there will be some header clashes until things are ported.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
Future work will be headed in the way of separating the policy supplied by
the nouveau drm module from the mechanisms provided by the driver core.
There will be a couple of major classes (subdev, engine) of driver modules
that have clearly defined tasks, and the further directory structure change
is to reflect this.
No code changes here whatsoever, aside from fixing up a couple of include
file pathnames.
