    sys/kern             vfs_bio.c 
  Log:
  Change the SMP wakeup() code to send an IPI to the target cpu's in parallel
  instead of chaining the message.  This fixes a stack depth assertion in the
  IPI processing code that Sephe was hitting in his network work.  The target
  cpu _wakeup() code no longer recurses the IPI subsystem.
