Implementation of a new "sys -t" option that displays kernel taint
information.  If the "tainted_mask" symbol exists, the option will
show its hexadecimal value and translate each bit set to the symbolic
letter of the taint type.  On kernels prior to 2.6.28 which had the
"tainted" symbol, only its hexadecimal value is shown.  The relevant
kernel sources should be consulted for the meaning of the letter(s)
or hexadecimal bit value(s).
