[PATCH 06/18] lib82596: move DMA allocation into the callers of i82596_probe
This allows us to get rid of the LIB82596_DMA_ATTR defined and prepare
for untangling the coherent vs non-coherent DMA allocation API.

[PATCH 11/17] sgiseeq: convert to dma_alloc_noncoherent
...including proper ownership transfers.
This includes adding additional calls to dma_sync_desc_dev as the
old syncing was rather ad-hoc.
Thanks to Thomas Bogendoerfer for debugging the ownership transfer
issues.

[PATCH 23/28] lib82596: convert from dma_cache_sync to dma_sync_single_for_device
Use the proper modern API to transfer cache ownership for incoherent DMA.
Note that this moves the DMA helpers to the main lib82596.c file, so
that they can use virt_to_dma.

[PATCH 11/18] lib82596: convert to dma_alloc_noncoherent
Use the new non-coherent DMA API including proper ownership transfers.
This includes moving the DMA helpers to lib82596 based of an ifdef to
avoid include order problems.

a saner API for allocating DMA addressable pages v3
Hi all,
this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs
with a separate new dma_alloc_pages API, which is available on all
platforms. In addition to cleaning up the convoluted code path, this
ensures that other drivers that have asked for better support for
non-coherent DMA to pages with incurring bounce buffering over can finally
be properly supported.
