Subject[PATCH v8 09/12] x86, hotplug: During CPU0 online, enable x2apic, set_numa_node.
Date
From: Fenghua Yu <fenghua.yu@intel.com>

Previously these functions were not run on the BSP (CPU 0, the boot processor)
since the boot processor init would only be executed before this functionality
was initialized.
