Simple buddy allocator. We want to allocate properly aligned power-of-two blocks to promote usage of huge-pages for the GTT, so 64K, 2M and possibly even 1G. While we do support allocating stuff at a specific offset, it is more intended for preallocating portions of the address space, say for an initial framebuffer, for other uses drm_mm is probably a much better fit. Anyway, hopefully this can all be thrown away if we eventually move to having the core MM manage device memory.

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.
