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:0000000cThis 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! --
