From ab583fc6402fc206eb2d216c3aa6e32317e9f087 Mon Sep 17 00:00:00 2001
From: Felix Kuehling <Felix.Kuehling@amd.com>

Subject: [PATCH 2820/2940] drm/amdkfd: Add chained_runlist_idle_disable flag
to pm4_mes_runlist
New flag to disable an idle runlist optimization that is causing soft
hangs with some diffult-to-reproduce customer workloads. This will
serve as a workaround until the problem can be reproduced and the
root-cause determined.
