From 47b178bb69ea4d0043f2df509c714bc5b287f375 Mon Sep 17 00:00:00 2001 From: Tim Anderson Date: Wed, 17 Jun 2009 16:25:18 -0700 Subject: MIPS: CMP: Move gcmp_probe to before the SMP ops This is to move the gcmp_probe call to before the use of and selection of the smp_ops functions. This allows malta with 1004K to work.
