[PATCH] init call cleanup
Trival patch for CPU hotplug. In CPU identify part, only did cleaup for intel CPUs. Need do for other CPUs if they support S3 SMP. Signed-off-by: Li Shaohua<shaohua.li@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
