  Modified files:
    sys/kern             kern_exec.c 
  Log:
  Conditionally acquire Giant when dropping a reference on the ktrace vnode
  during execve() when turning off tracing due to executing a setuid binary
  as non-root.  Previously this could fail to acquire Giant and fail an
  assertion if the ktrace file was on a non-MPSAFE filesystem and the
  executable was on an MPSAFE filesystem.
