From a355352b97901d987f54ea7c7d7161eb51a3799c Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Mon, 3 Mar 2008 14:12:58 -0300 Subject: [PATCH] x86: 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.
