    kern - Do not allow calls to vmspace_president_count() from userland.
    
    - Processes' vm_map is not read in by kvm_proclist() thus we cannot
      call vmspace_president_count() which entirely relies on that.
    - This fixes segfaults in ps(1), w(1) and fstat(1) when using -M
      and -N parameters.
