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.

[ Upstream commit 04c00956 ] The Scalable-mode Page-walk Coherency (SMPWC) field in the VT-d extended capability register indicates the hardware coherency behavior on paging structures accessed through the pasid table entry. This is ignored in current code and using ECAP.C instead which is only valid in legacy mode. Fix this so that paging structure updates could be manually flushed from the cache line if hardware page walking is not snooped.
