From: Glauber Costa <gcosta@...hat.com>
To: linux-kernel@...r.kernel.org
Cc: akpm@...ux-foundation.org, glommer@...il.com, mingo@...e.hu,
tglx@...utronix.de, Glauber Costa <gcosta@...hat.com>
Subject: [PATCH 30/52] move equal types to common file
move definitions that are now equal in type from
smpboot_{32,64}.c to smpboot.c
cpu_callin_map is put temporarily in smp_64.h (already
exists in smp_32.h), and will soon be merged.
Signed-off-by: Glauber Costa <gcosta@...hat.com>
