From 46ab6f24ac7b05c07e2936124b45da5f2f8fdc61 Mon Sep 17 00:00:00 2001 From: Shanghui Liu Date: Wed, 7 Jan 2015 16:58:22 +0530 Subject: [PATCH] MIPS: Netlogic: Fix wait for slave CPUs For core 0, the condition of "cpu == bootcpu" is always true, so it does not wait for other three threads to become ready. Fix this by using correct check.
