Chris Wilson 7d0aa0db43 drm/i915/gem: Unbind all current vma on changing cache-level
Avoid dangerous race handling of destroyed vma by unbinding all vma
instead. Unfortunately, this stops us from trying to be clever and only
doing the minimal change required, so on first use of scanout we may
encounter an annoying stall as it transitions to a new cache level.

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.
