Subject: [PATCH] MIPS: Remove a temporary hack for debugging cache flushes in SMTC configuration
Date: Fri, 5 Sep 2014 19:27:38 -0700 [thread overview]
Message-ID: <20140906022738.6957.53838.stgit@linux-yegoshin> (raw)

Author: Ralf Baechle <ralf@linux-mips.org>
Date: Wed Apr 5 09:45:45 2006 +0100
which is dropped now. Some performance degradation for multi-VPE systems
is removed.
