As the logic for selecting the register and corresponsing values grew, the code become a bit unsightly. Consolidate by storing the required values at engine init time in the engine itself, and by doing so minimise the amount of invariant platform and engine checks during each and every TLB invalidation. v2: * Fail engine probe if TLB invlidations registers are unknown. v3: * Rebase. v4: * Fix handling of GEN8_M2TCR. (Andrzej) v5: * Tidy checkpatch warnings.

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.
