  r300220 (by cem):
  
  sys/vmmeter.h: Fix trivial '-Wsign-compare' warning in common header
  
  Frankly, it doesn't make sense for vm_pageout_wakeup_thresh to have a negative
  value (it is only ever set to a fraction of v_free_min, which is unsigned and
  also obviously non-negative). But I'm not going to try and convert every
  non-negative scalar in the VM to unsigned today, so just cast it for the
  comparison.
  
  r300223 (by cem):
  
  vm/vm_page.h: Fix trivial '-Wpointer-sign' warning
  
  pq_vcnt, as a count of real things, has no business being negative. It is only
  ever initialized by a u_int counter.
  
  The warning came from the atomic_add_int() in vm_pagequeue_cnt_add().
  
  Rectify the warning by changing the variable to u_int. No functional change.
