Alex Deucher 16dc933a4f drm/amdgpu/userq: drop VCN and VPE doorbell handling
VCN and VPE userqs are not yet supported and this code is
not correct.  Userspace should provide the correct
doorbell offset with in their doorbell page for the IP.
Adjusting it here will not work as expected as userspace
and the queue itself will have different offsets.

We need to add a INFO IOCTL query to get the offset and
range for each IP within the doorbell page to handle this
properly.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
