From a5b45ded097908d40803b5c2770259398811b24e Mon Sep 17 00:00:00 2001 From: liguang Date: Thu, 30 May 2013 14:47:53 +0800 Subject: [PATCH] powerpc/smp: Use '==' instead of '<' for system_state 'system_state < SYSTEM_RUNNING' will have same effect with 'system_state == SYSTEM_BOOTING', but the later one is more clearer.
