My main motivation of this series is the last patch "mmc: sdhci: fix missing cache invalidation after reading by DMA".
Currently, read data are occasionally corrupted due to the missing cache invalidation.
To fix it nicely (adds dma_unmap_single(), which follows the Linux coding style), I did some cleaups first.
Patch 01-04 tidies up the DMA helpers.
Patch 05-10 are code clean-ups.
Patch 11 fixes the bug.
Masahiro Yamada (11): dma-mapping: fix the prototype of dma_map_single() dma-mapping: fix the prototype of dma_unmap_single() dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h> dma-mapping: add <asm/dma-mapping.h> for all architectures mmc: sdhci: put the aligned buffer pointer to struct sdhci_host mmc: sdhci: reduce code duplication for aligned buffer mmc: sdhci: use lower_32_bit2() and upper_32_bits() for setting adma_addr mmc: sdhci: remove unneeded casts mmc: add mmc_get_dma_dir() helper mmc: sdhci: use dma_map_single() instead of flush_cache() before DMA mmc: sdhci: fix missing cache invalidation after reading by DMA
