Subject: [PATCH v2 22/79] docs: mic: convert docs to ReST and rename to *.rst
Date:   Mon, 22 Apr 2019 10:27:11 -0300

Convert Intel Many Integrated Core architecture docs to ReST.

The conversion is trivial: just add title and literal block
markups, and adjust some identation.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
