From a0b00ca84b3ecb9eebd62ad34880d8cc0d988c8a Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Fri, 10 Jul 2009 10:04:56 +0900 Subject: [PATCH] ia64: add dma_capable() to replace is_buffer_dma_capable() dma_capable() eventually replaces is_buffer_dma_capable(), which tells if a memory area is dma-capable or not. The problem of is_buffer_dma_capable() is that it doesn't take a pointer to struct device so it doesn't work for POWERPC.
