x86: provide specialized identification routines for x86_64
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 Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
