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 Signed-off-by: NDaniel J Blueman <daniel@numascale.com> Signed-off-by: NBorislav Petkov <bp@suse.de> Cc: <stable@vger.kernel.org> Cc: H.
