x86: clean up non-smp usage of cpu maps
Cleanup references to the early cpu maps for the non-SMP configuration and remove some functions called for SMP configurations only. Cc: Andi Kleen <ak@suse.de> Cc: Christoph Lameter <clameter@sgi.com> Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
