Subject: [PATCH 0/5] Add debugfs info for the AMD IOMMU

The following series creates a debugfs directory for AMD IOMMUs,
constructs a framework for additional entries, an online README,
and a method for dumping device table entries. Data is reported
in a default concise mode, but a verbose mode is enabled via a
filesystem entry.

This is the first of three patch series that will expose a number
of IOMMU registers.
