Subject[PATCH v2 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.

Changes since v1:
- Correctly use CONFIG_AMD_IOMMU_DEBUG in Makefile and header file


Gary R Hook (5):
iommu/amd - Add debugfs support
iommu/amd - Add a 'verbose' switch for IOMMU debugfs
iommu/amd - Add a README variable for the IOMMU debugfs
iommu/amd - Expose the active IOMMU device table entries
iommu/amd - Add a debugfs entry to specify a IOMMU device table entry
