Add page reclamation related changes to GuC interface, handlers, and senders to support page reclamation. Currently TLB invalidations will perform an entire PPC flush in order to prevent stale memory access for noncoherent system memory. Page reclamation is an extension of the typical TLB invalidation workflow, allowing disabling of full PPC flush and enable selective PPC flushing. Selective flushing will be decided by a list of pages whom's address is passed to GuC at time of action. Page reclamation interfaces require at least GuC FW ver 70.31.0. v2: - Moved send_page_reclaim to first patch usage. - Add comments explaining shared done handler. (Matthew B) - Add FW version fallback to disable page reclaim on older versions.

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 reStructuredText 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.
