From 36d29edb6dded938bf07f741a0bb0f2a7116e617 Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Thu, 27 Mar 2008 14:59:58 +1100 Subject: [POWERPC] spufs: save MFC command channel before purging MFC queue During the context save process, we currently save the MFC command channel after purging the MFC queues. This causes a systemsim warning, as the command channel may be in an unknown state after the purge. This change does the save before purging the MFC queues.
