From b2788965baed868ce48ebd6d67f00acf617c9ee6 Mon Sep 17 00:00:00 2001 From: Hillf Danton Date: Sat, 24 Sep 2011 02:29:54 +0200 Subject: [PATCH] MIPS: XLR, XLS: Add comment for smp setup It seems that BSP could be setup twice, but the nlm_cpu_ready array is only set for ASPs in smpboot.S, not including BSP.
