From 7927096868061ff10fdb33b295dc0bcfebe2b35b Mon Sep 17 00:00:00 2001 From: Ross Zwisler Date: Wed, 14 May 2014 09:41:12 -0600 Subject: [PATCH] drm: Missed clflushopt in drm_clflush_virt_range With this commit: 2a0788dc9bc4 x86: Use clflushopt in drm_clflush_virt_range If clflushopt is available on the system, we use it instead of clflush in drm_clflush_virt_range. There were two calls to clflush in this function, but only one was changed to clflushopt. This patch changes the other clflush call to clflushopt.
