    sys/kern             kern_xio.c 
  Log:
  Fix bugs in xio_copy_*().  We were not using the masked offset when
  calculation the number of bytes to copy from the first indexed page,
  leading to a negative 'n' calculation in situations that could be
  triggered with a ^C on programs using pipes (such as a buildworld).
  This almost universally resulted in a panic.
