Merge branch 'cleanups/dma' into next/cleanup
Separate patches from Marek Szyprowski <m.szyprowski@samsung.com>:
Commit e9da6e9905e639b0 ("ARM: dma-mapping: remove custom consistent dma
region") replaced custom consistent memory handling, so setting
consistent dma memory size is not longer required. This patch series
cleans sub-architecture platform code to remove all calls to the
obsolated init_consistent_dma_size() function and finally removes the
init_consistent_dma_size() stub itself.
* cleanups/dma:
ARM: at91: remove obsoleted init_consistent_dma_size()
ARM: u300: remove obsoleted init_consistent_dma_size()
ARM: dma-mapping: remove init_consistent_dma_size() stub
ARM: shmobile: remove obsoleted init_consistent_dma_size()
ARM: davinci: remove obsoleted init_consistent_dma_size()
ARM: samsung: remove obsoleted init_consistent_dma_size()
