	the topology (on my POWERPC5+ box) is not correct:

cpu0/topology/thread_siblings:0000000f
cpu1/topology/thread_siblings:0000000f
cpu2/topology/thread_siblings:0000000f
cpu3/topology/thread_siblings:0000000f

it used to be:

cpu0/topology/thread_siblings:00000003
cpu1/topology/thread_siblings:00000003
cpu2/topology/thread_siblings:0000000c
cpu3/topology/thread_siblings:0000000c
This would be because we are setting up the cpu_sibling map before we
call setup_per_cpu_areas().
The following patch hopefully should fix this problem.  I'm
not able to build or test it but the few references to 
cpu_sibling_map seem to all occur well after setup_per_cpu_areas
is called.

Thanks Stephen for checking this out!
