Subject: [PATCH v3 0/2] OMAP:IOMMU:flush L1 and L2 caches

This patch series is the next version to
- add a new cache maintenance api to support non-coherent iommu drivers.
- flush both L1 and L2 caches from OMAP iommu whenever the page table
  memory is updated.

Changes since the previous patch set
- Renamed the new api to reflect the purpose.
- Fixed the kernel compilation issues by adding the
  new api support for all the ARM versions.
- Validated the changes on the Pandaboard.
- Compile tested the kernel for all other ARM configurations.

The implementation of the new api is based on
the approach[1] discussed.
