  Modified files:
    sys/sys              buf.h 
  Log:
  The BUF_*() routines must be internally splbio() protected otherwise they
  can cause a biodone() from a disk interrupt to spin when the interrupt
  code tries to grab the simplelock.  Masking BIO here means buftimelock
  and/or lk->lk_interlock shouldn't be held when an interrupt tries to grab
  them.
