[PATCH v12 2/7] x86, acpi, cpu-hotplug: Enable acpi to register all possible cpus at boot time.

From: Gu Zheng [Problem] cpuid <-> nodeid mapping is firstly established at boot time. And workqueue caches the mapping in wq_numa_possible_cpumask in wq_numa_init() at boot time. When doing node online/offline, cpuid <-> nodeid mapping is established/destroyed, which means, cpuid <-> nodeid
