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 and 02 fix the prototypes of dma_{map,unmap}_single().
Patch 03-08 are code clean-ups.
Patch 09 fixes the bug.
