This patchset removes useless sync_single_range_for_cpu and
sync_single_range_for_device hooks in dma_map_ops. These hooks were
for dma_sync_single_range_* DMA API, however, the API became obsolete
(the description in DMA API docs was removed too). Architecutres
should use sync_single_for_cpu and sync_single_for_device hooks
instead (as DMA API docs say, they need to support a partial sync).
We could remove dma_sync_single_range_* DMA API completely (no user in
-mm) but the API had been until 2.6.34-rc so I guess that it might be
better to leave it alone for some time.
The first patch is a bug fix and might be 2.6.34-rc material however
the API is not so popular (only net/b44.c uses) and we are already in
-rc5. I guess that it would be fine to merge it in the next merge
window.
