If used for this purpose then we must add a new TAINT flag for
proc_taint() was used, otherwise we can cheat to show a taint
*did* happen, where in fact it never happened, some punk just
echo'd a value into the kernel's /proc/sys/kernel/tainted.

Forunately proc_taint() only allows to *increment* the taint, not
reduce.
