Subject: [PATCH 2/3] powerpc/pseries: Disable PRRN memory device tree trigger
Date: Wed, 15 May 2019 21:37:05 -0500	[thread overview]
Message-ID: <20190516023706.50118-2-tyreld@linux.ibm.com> (raw)
In-Reply-To: <20190516023706.50118-1-tyreld@linux.ibm.com>

Memory affintiy updates as currently implemented have proved unstable.

This patch comments out the PRRN hook for the time being while we
investigate how to either stablize the current implementation or find a
better approach.
