Linux kernel source tree

TLB cache invalidation can happen on two different situations: 1. synchronously, at __vma_put_pages(); 2. asynchronously. On the first case, TLB cache invalidation happens inside __vma_put_pages(). So, no need to do it later on. However, on the second case, the pages will keep in memory until __i915_vma_evict() is called. So, we need to store the TLB data at struct i915_vma_resource, in order to do a TLB cache invalidation before allowing userspace to re-use the same memory. So, i915_vma_resource_unbind() has gained a new parameter in order to store the TLB data at the second case. Document it.

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.
