[PATCH -v2 0/7] powerpc: use asm-generic/dma-mapping-common.h

[FUJITA Tomonori]

This is the second version of the patchset to convert POWERPC to use
asm-generic/dma-mapping-common.h:

http://marc.info/?l=linux-kernel&m=124840628128189&w=2

There are some minor changes since the first version are:

- removed unused CONFIG_PPC_NEED_DMA_SYNC_OPS [5/7] (Becky pointed
  out).

- added Becky's Acked-by

- added two new patches ([6/7] and [7/7]). [6/7] fixes SWIOTLB's
  dma_mapping_error(). [7/7] addes CONFIG_DMA_API_DEBUG support.


This is on the top of my swiotlb cleanup patchset:

http://marc.info/?l=linuxppc-embedded&m=124718920320951&w=2


The above swiotlb patchset was merged in -tip so I think that merging
this patchset via -tip too is the easiest way to handle this patchset.

The patchset also is available via a git tree:
