x86/apic/numachip: Fix sibling map with NumaChip
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
