On NumaChip systems, the physical processor ID assignment wasn't
accounting for the number of nodes in AMD multi-module
processors, giving an incorrect sibling map:

  $ cd /sys/devices/system/cpu/cpu29/topology
  $ grep . *
  core_id:5
  core_siblings:00000000,ff000000
  core_siblings_list:24-31
  physical_package_id:3
  thread_siblings:00000000,30000000
  thread_siblings_list:28-29

This fixes it:

  $ cd /sys/devices/system/cpu/cpu29/topology
  $ grep . *
  core_id:5
  core_siblings:00000000,ffff0000
  core_siblings_list:16-31
  physical_package_id:1
  thread_siblings:00000000,30000000
  thread_siblings_list:28-29
