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:

Quoted 7 lines
Quoted 4 lines

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!
