Due to wrong `.. kernel-doc` directive in Documentation/gpu/rfc/gpusvm.rst
the documentation was actually not parsing anything from
drivers/gpu/drm/drm_gpusvm.c. This fixes the kernel-doc include and all
warnings/errors created when doing so.

DMEM cgroup pull request

This code is based on the RDMA and misc cgroup initially, but now
uses page_counter. It uses the same min/low/max semantics as the memory
cgroup as a result.
There's a small mismatch as TTM uses u64, and page_counter long pages.
In practice it's not a problem. 32-bits systems don't really come with
>=4GB cards and as long as we're consistently wrong with units, it's
fine. The device page size may not be in the same units as kernel page
size, and each region might also have a different page size (VRAM vs GART
for example).
The interface is simple:
- Call dmem_cgroup_register_region()
- Use dmem_cgroup_try_charge to check if you can allocate a chunk of memory,
use dmem_cgroup__uncharge when freeing it. This may return an error code,
or -EAGAIN when the cgroup limit is reached. In that case a reference
to the limiting pool is returned.
- The limiting cs can be used as compare function for
dmem_cgroup_state_evict_valuable.
- After having evicted enough, drop reference to limiting cs with
dmem_cgroup_pool_state_put.
This API allows you to limit device resources with cgroups.
You can see the supported cards in /sys/fs/cgroup/dmem.capacity
You need to echo +dmem to cgroup.subtree_control, and then you can
partition device memory.

Panels using a PWM-controlled backlight source do not have a standard
way to communicate their valid PWM ranges.
On x86 the ranges are read from ACPI through driver-specific tables.
The built-in ranges are not necessarily correct, or may grow stale if an
older device can be retrofitted with newer panels.
Add a quirk infrastructure with which the minimum valid backlight value
can be maintained as part of the kernel.

Currently it is not well defined what is drm-memory- compared to other
categories.
In practice the only driver which emits these keys is amdgpu and in them
exposes the current resident buffer object memory (including shared).
To prevent any confusion, document that drm-memory- is deprecated and an
alias for drm-resident-memory-.
While at it also clarify that the reserved sub-string 'memory' refers to
the memory region component, and also clarify the intended semantics of
other memory categories.
v2:
* Also mark drm-memory- as deprecated.
* Add some more text describing memory categories. (Alex)
v3:
* Semantics of the amdgpu drm-memory is actually as drm-resident.

This commit introduces a DRM device sysfs attribute that lets UM control
the job accounting status in the device. The knob variable had been brought
in as part of a previous commit, but now we're able to fix it manually.
As sysfs files are part of a driver's uAPI, describe its legitimate input
values and output format in a documentation file.
