/sys/devices/system/cpu/*: Present cpus or Possible cpus

Hi! Looking at the topology_init() code, I observe that the meaning of the cpuX/ directory entries in /sys/devices/system/cpu/ might be different for different architectures. Looks like, in case of i386, ia64, m32, mips etc, the cpuX directory entries represent the "present cpus". However, in c
