    kernel - Fix crypto boots and rescue boots
    
    * The kernel text+data+bss is too big, the loader's 64MB heap can't fit
      it plus modules plus the initrd image any more.  Fix by reducing the
      kernel's BSS.
    
    * Reduce the BSS allocation for CPU_prvspace[] from 11MB (45056 x 256 cpus)
      to ~45056 for the BSP and dynamically allocate the globaldata space for
      the APs.  Also saves ~11MB of ram or so on normal systems.
    
    * Reduce the BSS allocation for cpu_map_entry_init[].  Only the BSP needs
      MAXCPU+1 pre-cached vm_map_entry structures.  The APs can make due with
      8 or so before the VM system comes up sufficiently to dynamically allocate
      these structures.  This saves around ~6.5MB of ram on normal systems.
