From d72944457bb7d5c4be43aa1b741cb93c69484c20 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 8 Mar 2011 13:50:37 +1100 Subject: [PATCH] powerpc/smp: Add a smp_ops->bringup_up() done callback This allows us to stop abusing smp_ops->setup_cpu() for cleanup tasks that have to take place after the initial boot time CPU bringup.
