Subject[PATCH 07/79] [PATCH] provide specialized identification routines for x86_64
Date
From: Glauber Costa <gcosta@redhat.com>

provide two specialized identify_secondary_cpu() and identify_boot_cpu()
routines for x86_64. Although not strictly needed, they are functionally
correct, and will ease integration with i386
