To maintain a fast lookup from a GT centric irq handler, we want the engine lookup tables on the intel_gt. To avoid having multiple copies of the same multi-dimension lookup table, move the generic user engine lookup into an rbtree (for fast and flexible indexing). v2: Split uabi_instance cf uabi_class v3: Set uabi_class/uabi_instance after collating all engines to provide a stable uabi across parallel unordered 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.
