MOVDIRI moves doubleword or quadword from register to memory through direct store which is implemented by using write combining (WC) for writing data directly into memory without caching the data. Availability of the MOVDIRI instruction is indicated by the presence of the CPUID feature flag MOVDIRI(CPUID.0x07.0x0:ECX[bit 27]). This patch exposes the movdiri feature to the guest.

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.
