[PATCH] ia64: fix noncoherent DMA API so devres builds
On ia64, drivers/base/dma-mapping.c doesn't build because it calls dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be terminally broken; the calls end up generating errors like drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release': drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent' because the multiple levels of macro expansion in <asm/dma-mapping.h> and <asm/machvec.h> end up turning a call to dma_free_noncoherent() into ia64_mv.platform_dma_free_coherent (instead of the intended ia64_mv.dma_free_coherent). This patch fixes this by converting dma_{alloc,free}_noncoherent() into inline functions that call the corresponding coherent functions, instead of trying to do this with macros.
