Subject: [PATCH v5 0/2] ARM: New cache API for iommu

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 (v4)
- Fixed RMK's comments on the api params.
- Validated the changes on the Panda board.
- Compile tested the kernel for all other ARM configurations.

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