Subject[PATCH v3 0/2] Base enablement of IOMMU debugfs support
From
Date
These patches create a top-level function to create a debugfs directory
for the IOMMU, under which drivers may create and populate-specific
directories for their device internals.

Patch 1: general IOMMU enablement
Patch 2: basic AMD enablement to demonstrate linkage with patch 1

Introduce a new Kconfig parameter IOMMU_DEBUG to globally allow or
disallow debugfs code to be built.

Changes since v2:
- Move a declaration to outside an ifdef
- Remove a spurious blank line

Changes since v1:
- Remove debug cruft
- Remove cruft produced by design change
- Change the lock to a mutex
- Coding style fixes
- Add a comment to document the framework
