Hopefully not needed anymore. We can add a .compatible() hook once we
need to differentiate between mappable and non-mappable vram. If the
allocation is not contiguous then the start value is kind of
meaningless, so rather just mark as invalid.
In upstream, TTM wants to eventually remove the ttm_resource.start
usage.

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 Restructured Text 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.
