[PATCH 54/79] [PATCH] provide an end_local_APIC_setup function

From: Glauber de Oliveira Costa
Date: Wed Mar 19 2008 - 16:14:03 EST


From: Glauber Costa <gcosta@xxxxxxxxxx>

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.
