From ac60aae561fff99d38beba82d84277b12437c05e Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 19 Mar 2008 14:25:49 -0300 Subject: [PATCH] x86: provide an end_local_APIC_setup function It splits setup_local_APIC in two, providing a function corresponding to the ending part of it. As a side effect, smp_callin looks the same between i386 and x86_64.
