Our eventual goal is to rid request construction of struct_mutex, with the short term step of lifting the struct_mutex requirements into the higher levels (i.e. the caller must ensure that the context is already pinned into the GTT). In this patch, we pin GVT's shadow context upon allocation and so keep them pinned into the GGTT for as long as the virtual machine is alive, and so we can use the simpler request construction path safe in the knowledge that the hard work is already done.

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.
