From 023600f192be3f5776336e2c61d577b551a1ca9c Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Tue, 26 May 2015 18:02:54 +0900 Subject: swiotlb: do not export map_single function The map_single() function is not defined as static, even though it doesn't seem to be used anywhere else in the kernel. Make it static to avoid namespace pollution since this is a rather generic symbol.
