Subject: [PATCH 0/8] MIPS: Use dma-mapping-common.h and use swiotlb for Octeon (v2).

v2:
 o Eliminated changes to generic swiotlb code.

 o Indirect calls to phys_to_dma() and dma_to_phys() moved to Octeon
   specific code.

 o Clean up platform hook for swiotlb setup.

from v1:

The Octeon family of SOCs support physical memory outside of the
32-bit addressing range.  To support 32-bit devices, we need to use
the swiotlb bounce buffer mechanism.

There are several parts to the patch set.

1 -     Set the proper dma_masks for the octeon_mgmt platform device so
        that it continues to function with the rewritten dma mapping
        code to follow.

2,3,4 - Establish a properly constrained DMA32 zone for Octeon.

5 -     Make some existing functions static inline.

6 -     Convert MIPS to use dma-mapping-common.h

7 -     Get MIPS ready to use swiotlb.

8 -     Rewrite Octeon dma mapping code.

David Daney (8):
  MIPS: Octeon: Set dma_masks for octeon_mgmt device.
  MIPS: Allow MAX_DMA32_PFN to be overridden.
  MIPS: Octeon: Adjust top of DMA32 zone.
  MIPS: Octeon: Select ZONE_DMA32
  MIPS: ip32, ip27, jazz: Make static functions in dma-coherence.h
    inline.
  MIPS: Convert DMA to use dma-mapping-common.h
  MIPS: Add a platform hook for swiotlb setup.
  MIPS: Octeon: Rewrite DMA mapping functions.
