  Modified files:        (Branch: RELENG_4)
    sys/i386/i386        machdep.c swtch.s 
  Log:
  MFC revisions 1.464 and 1.115 of machdep.c and swtch.s respectively to
  provide better handling of reserved debug register bits; allows
  debuggers to write back the unmodified value of dr7 that they received
  from the traced process's PCB without it failing with EINVAL, while
  still preserving reserved bit settings for the CPU.
