cpu_proc_init() does processor specific initialization, which we do at boot time. We have been omitting to do this on resume, which causes some of this initialization to be skipped. We've also been skipping this on SMP initialization too. Ensure that cpu_proc_init() is always called appropriately by moving it into cpu_init(), and move cpu_init() to a more appropriate point in the boot initialization.
