Supplement the per-engine HWSP with a per-timeline HWSP. That is a per-request pointer through which we can check a local seqno, abstracting away the presumption of a global seqno. In this first step, we point each request back into the engine's HWSP so everything continues to work with the global timeline. v2: s/i915_request_hwsp/hwsp_seqno/ to emphasis that this is the current HW value and that we are accessing it via i915_request merely as a convenience.

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.
