c2bbf9d1e9 dma-debug: teach add_dma_entry() about DMA_ATTR_SKIP_CPU_SYNC 
Mapping something twice should be possible as long as,
DMA_ATTR_SKIP_CPU_SYNC is passed to the strictly speaking second relevant
mapping operation (that attempts to map the same thing). So, don't issue a
warning if the specified condition is met in add_dma_entry().

a1fd09e8e6 dma-mapping: move dma-debug.h to kernel/dma/ 
Most of dma-debug.h is not required by anything outside of kernel/dma.
Move the four declarations needed by dma-mappin.h or dma-ops providers
into dma-mapping.h and dma-map-ops.h, and move the remainder of the
file to kernel/dma/debug.h.
