drm/nouveau/instmem/gk20a: use direct CPU access
The Great Nouveau Refactoring Take II brought us a lot of goodness,
including acquire/release methods that are called before and after an
instobj is modified. These functions can be used as synchronization
points to manage CPU/GPU coherency if we modify an instobj using the
CPU.
This patch replaces the legacy and slow PRAMIN access for gk20a instmem
with CPU mappings and writes. A LRU list is used to unmap unused
mappings after a certain threshold (currently 1MB) of mapped instobjs is
reached. This allows mappings to be reused most of the time.
Accessing instobjs using the CPU requires to maintain the GPU L2 cache,
which we do in the acquire/release functions. This triggers a lot of L2
flushes/invalidates, but most of them are performed on an empty cache
(and thus return immediately), and overall context setup performance
greatly benefits from this (from 250ms to 160ms on Jetson TK1 for a
simple libdrm program).
Making L2 management more explicit should allow us to grab some more
performance in the future.

On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.
This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up

This binding follows the model of msm, imx, sti, and others, where
there is a subsystem node for the whole GPU, with nodes for the
individual HW components within it.

Compared to wrapping the final kref_put with dev->struct_mutex this
allows us to only acquire the offset manager look both in the final
cleanup and in the lookup. Which has the upside that no locks leak out
of the core abstractions. But it means that we need to hold a
temporary reference to the object while checking mmap constraints, to
make sure the object doesn't disappear. Extended the critical region
would have worked too, but would result in more leaky locking.
Also, this is the final bit which required dev->struct_mutex in gem
core, now modern drivers can be completely struct_mutex free!

drm/vgem: drop DRIVER_PRIME (v2)
for now, so this is dead code. And since I want to rework the locking
for drm_gem_mmap it seems simpler to de-dupe this code for now and
then start over with the reworked one again, if we want to resurrect
this all indeed.

drm: Fix return value of drm_framebuffer_init()
In its original version, drm_framebuffer_init() returned a negative int
if drm_mode_object_get() failed (
f453ba046074, "DRM: add mode setting
support").
This was accidentally disabled by commit
4b096ac10da0 ("drm: revamp
locking around fb creation/destruction"). Thus, drm_framebuffer_init()
pretends success if drm_mode_object_get() failed.
Reinstate the original behaviour. Also fix erroneous kernel-doc of
drm_mode_object_get().

drm/doc: Rename docbook to gpu.tmpl
DRM is a lot more than a direct rendering manager nowadays, and there's
also a bunch of things worth documenting for gpu driver developers
outside of drivers/gpu/drm, like vgaarb, vga_switcheroo or the various
hardware buses like host1x and ipu-v3.
To avoid further confusion let's rename the top-level to reflect
reality.
And yes I'm already looking forward to when we need to replace the G
in GPU with a * ;-)
Inspired by a thread with Lukas since he refused to include the
vga_switcheroo docs into the drm docs because it's not drm.

drm/<drivers>: Drop DRM_UNLOCKED from modeset drivers
Just one special case (since i915 lost its ums code, yay):
- radeon: Has slots for the old ums ioctls which don't have
DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it
everywhere.
Every other kms driver just has DRM_UNLOCKED for all their ioctls, as
they should.
v2: admgpu happened, include that one too. And i915 lost its UMS

drm: Enforce unlocked ioctl operation for kms driver ioctls
With the prep patches for i915 all kms drivers either have
DRM_UNLOCKED on all their ioctls. Or the ioctl always directly returns
with an invariant return value when in modeset mode. But that's only
the case for i915 and radeon. The drm core ioctls are unfortunately
too much a mess still to dare this.
Follow-up patches will remove DRM_UNLOCKED from all kms drivers to
prove that this is indeed the case.
Also update the documentation.
v2: Really only do this for driver ioctls, spotted by David Herrmann.
