From c3b6167ab9d36b52fb56e02fe767229e8f6c4546 Mon Sep 17 00:00:00 2001
From: Felix Kuehling <Felix.Kuehling@amd.com>
Date: Tue, 28 Feb 2017 15:19:53 -0500
Subject: [PATCH 1236/4131] drm/amdkfd: Print rate-limited messages for all
evictions
This can probably be replaced with traces later on. For now this should
help us track down unexpected evictions and give user mode teams an
indication when frequent evictions are responsible for performance
problems.
