From 51ef2756d9b88b590d80b2fc552a7ea54e65aaa4 Mon Sep 17 00:00:00 2001
From: Yong Zhao <Yong.Zhao@amd.com>
Date: Thu, 7 Nov 2019 23:18:04 -0500
Subject: [PATCH 4435/4736] drm/amdkfd: Merge CIK kernel queue functions into
VI
The only difference that CIK kernel queue functions are different from
VI is avoid allocating eop_mem. We can achieve that by using a if
condition.
