Log:
  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.
