 This looks good in general.  Some suggestions:
 
 In fill_pcpu():
 - Use 'kvm_getmaxcpu' instead of 'kvm_getcptime' in error message.
 - I think it's ok to just drop the maxcpu == 0 check.
 - I would just use 'calloc(maxcpu, sizeof(struct pcpu *))' and
   have the error just say that calloc() failed w/o including the
   size.
 - C doesn't require a cast for void * pointers, so you can remove
   the cast from calloc().
 - Always use a space after 'if' and let the first { of a function
   start on a new line.
 - I would probably use 'pcpu' instead of 'ppcpup' as the variable
   name.
 
 These are fairly minor nits though.  I can probably fix these things and test 
 it today.
