From 6b42a7eafb25ae9fda1708c501661384d1f60482 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Fri, 25 Oct 2013 10:33:27 +0000 Subject: [PATCH] swiotlb-xen: static inline xen_phys_to_bus, xen_bus_to_phys, xen_virt_to_bus and range_straddles_page_boundary This functions are small and called frequently. Static inline them.
