dma-mapping: turn dma_cache_sync into a dma_map_ops method (2017-10-19 16:37:49 +0200)

----------------------------------------------------------------
A couple of dma-mapping updates:

- turn dma_cache_sync into a dma_map_ops instance and remove
implementation that purely are dead because the architecture
doesn't support noncoherent allocations
- add a flag for busses that need DMA configuration (Robin Murphy)

----------------------------------------------------------------
Christoph Hellwig (11):
floppy: consolidate the dummy fd_cacheflush definition
x86: make dma_cache_sync a no-op
frv: make dma_cache_sync a no-op
ia64: make dma_cache_sync a no-op
microblaze: make dma_cache_sync a no-op
mn10300: make dma_cache_sync a no-op
powerpc: make dma_cache_sync a no-op
unicore32: make dma_cache_sync a no-op
xtensa: make dma_cache_sync a no-op
sh: make dma_cache_sync a no-op
dma-mapping: turn dma_cache_sync into a dma_map_ops method

Robin Murphy (1):
drivers: flag buses which demand DMA configuration
