[PATCH] MAINTAINERS: Add myself as an AMD SVM & IOMMU reviewer

[Jason Andryuk]

Split out AMD SVM and AMD IOMMU, and add myself as a reviewer.  Jan,
Andrew and Roger are set as maintainers as they were for the X86 entry.

Thanks for adding yourself!

I have on question below about the mechanics of MAINTAINERS parsing
(but no objection at all with you becoming a reviewer).

Would it be possible to not exclude the SVM related code here, and
avoid having to duplicate the x86 maintainers on the AMD entries?

Or the parsing of the file doesn't deal with multiple entries possibly
covering the same files?

Thanks, Roger.

./get_maintainer.pl can deal with a file been covered by multiple
entries, there's multiple example of that already, (e.g. many subsection
are also covered by TOOLSTACK).

The exclusion is likely unnecessary, and ./get_maintainer.pl will just
get the information (email, ...) from every sections that a file match.
But the duplication is necessary due to the "The meaning of nesting"
described in the MAINTAINERS file.

Roger, are you okay with this approach?

I considered adding myself to the top level X86 entry but it covers so 
much.  I mainly care about one cpu vendor ;) and I'm not interested in 
PV or shadow.  So I went with adding myself to the specific subset.

Regards,
Jason

Indeed.  Jan reported a sorting issue, you can add my:

Acked-by: Roger Pau Monné <roger.pau@citrix.com>

To the correctly sorted patch.

Thanks, Roger.

Nit: These are the wrong way round, violating alphabetical sorting.
