From f98eee8ea99fe74ee9c4e867ba178ec3072793be Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 5 Jan 2009 23:59:03 +0900 Subject: x86, ia64: remove duplicated swiotlb code This adds swiotlb_map_page and swiotlb_unmap_page to lib/swiotlb.c and remove IA64 and X86's swiotlb_map_page and swiotlb_unmap_page. This also removes unnecessary swiotlb_map_single, swiotlb_map_single_attrs, swiotlb_unmap_single and swiotlb_unmap_single_attrs.
