[PATCH] ia64: re-implement dma_get_cache_alignment to avoid EXPORT_SYMBOL
The current ia64 implementation of dma_get_cache_alignment does not work for modules because it relies on a symbol which is not exported. Direct access to a global is a little ugly anyway, so this patch re-implements dma_get_cache_alignment in a manner similar to what is currently used for x86_64. Signed-off-by: John W.
