Linux kernel source tree

There's no reason that I can tell why this should be per-i915_buddy_mm
and doing so causes KMEM_CACHE to throw dmesg warnings because it tries
to create a debugfs entry with the name i915_buddy_block multiple times.
We could handle this by carefully giving each slab its own name but that
brings its own pain because then we have to store that string somewhere
and manage the lifetimes of the different slabs. The most likely
outcome would be a global atomic which we increment to get a new name or
something like that.
The much easier solution is to use the i915_globals system like we do
for every other slab in i915. This ensures that we have exactly one of
them for each i915 driver load and it gets neatly created on module load
and destroyed on module unload. Using the globals system also means
that its now tied into the shrink handler so we can properly respond to
low-memory situations.

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.
