From 57bf5a8963f80fb3828c46c3e3a5b2dd790e09a7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 22 Dec 2017 16:05:15 +0100 Subject: dma-mapping: clear harmful GFP_* flags in common code Lift the code from x86 so that we behave consistently. In the future we should probably warn if any of these is set.
