Ok, fair enough. So I'll change my asm-generic/types.h to use
#ifndef dma_addr_t
#ifdef CONFIG_PHYS_ADDR_T_64BIT
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif /* CONFIG_PHYS_ADDR_T_64BIT */
#endif /* dma_addr_t */
If you eventually want to use the the generic version, you
just need to add
#define dma_addr_t dma_addr_t
before the #include. Or you just ignore the asm-generic version
and don't have to do anything.
