From 1b0fac45878bb88759eec347c273285195649ff7 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Sun, 15 Jul 2007 23:40:26 -0700 Subject: dma-mapping: prevent dma dependent code from linking on !HAS_DMA archs Continuing the work started in 411f0f3edc141a582190d3605cadd1d993abb6df ... This enables code with a dma path, that compiles away, to build without requiring additional code factoring. It also prevents code that calls dma_alloc_coherent and dma_free_coherent from linking whereas previously the code would hit a BUG() at run time. Finally, it allows archs that set !HAS_DMA to delete their asm/dma-mapping.h file. Cc: Cornelia Huck Cc: Martin Schwidefsky Cc: Heiko Carstens Cc: John W.
