From d26dbc5cf94b0a28acc947285c3b54814a73cb2e Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Date: Mon, 22 Sep 2008 22:35:07 +0900 Subject: iommu: export iommu_area_reserve helper function x86 has set_bit_string() that does the exact same thing that set_bit_area() in lib/iommu-helper.c does. This patch exports set_bit_area() in lib/iommu-helper.c as iommu_area_reserve(), converts GART, Calgary, and AMD IOMMU to use it.
