Mauro says:

	This patch series fix Sphinx to allow it to build the media
	documentation as a PDF file.

	The first patch is actually a bug fix: one of the previous patch
	broke compilation for PDF as a hole, as it added an extra
	parenthesis to a function call.

	The second patch just removes a left over code for rst2pdf.

	The other patches change from "pdflatex" to "xelatex" and address
	several issues that prevent building the media books.

	I think this patch series belong to docs-next. Feel free to merge
	them there, if you agree. There's one extra patch that touches
	Documentation/conf.py, re-adding the media book to the PDF build,
	but IMHO this one would be better to be merged via the media tree,
	after the fixes inside the media documentation to fix the build.

This extension will be used by the media books.

The output for those notes are bad in pdf, as they're not
in a box with a different color. Also, it causes the output
to not build if the note is inside a table.

Change its implementation to avoid the above troubles.

Hi Jon,

This patch is an old one, we have corrected some minor issues on the newer one.
Please only review the newest version from my last mail with this subject
"[PATCH] ACPI: Update the maximum depth of C-state from 6 to 9".
And I also attached it to this mail.

Thanks,
