From 9dfda12b8b769e224ca4efbc35ace4524b9c017b Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 8 Sep 2008 18:53:48 +0900 Subject: swiotlb: use map_single instead of swiotlb_map_single in swiotlb_alloc_coherent We always need swiotlb memory here so address_needs_mapping and swiotlb_force testings are irrelevant. map_single should be used here instead of swiotlb_map_single.
