Start acquiring the logical intel_context and using that as our primary means for request allocation. This is the initial step to allow us to avoid requiring struct_mutex for request allocation along the perma-pinned kernel context, but it also provides a foundation for breaking up the complex request allocation to handle different scenarios inside execbuf. For the purpose of emitting a request from inside retirement (see the next patch for engine power management), we also need to lift control over the timeline mutex to the caller. v2: Note that the request carries the active reference upon construction.

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.
