  Modified files:
    sys/kern             kern_sysctl.c 
  Log:
  In sysctl, req->td is believed always to be non-NULL, so there's no need
  to test req->td for NULL values and then do somewhat more bizarre things
  relating to securelevel special-casing and suser checks.  Remove the
  testing and conditional security checks based on req->td!=NULL, and insert
  a KASSERT that td != NULL.  Callers to sysctl must always specify the
  thread (be it kernel or otherwise) requesting the operation, or a
  number of current sysctls will fail due to assumptions that the thread
  exists.
