From: Michel Dänzer <michel.daenzer@amd.com>

Subject: [PATCH 3/20]present: Support async flips
Patch-mainline: Upstream
Git-repo: git://anongit.freedesktop.org/xorg/driver/xf86-video-ati
Git-commit: 1ca677309720e2f6c953c9e76f5b34c22a4416c6
References: bsc#990066
Signed-off-by: Max Staudt <mstaudt@suse.de>

The xserver Present code only calls radeon_present_flip with
sync_flip=FALSE if radeon_present_screen_init sets
PresentCapabilityAsync, and the latter only sets it if the kernel driver
advertises support for async flips.
