[PATCH] blacklist more unsafe functions

[Timo Juhani Lindfors]

These were found empirically. Some of the functions look innocent but
they are called from functions marked with __kprobes so they still
cause crashes. Further analysis is available at
https://lkml.org/lkml/2013/2/27/82 ("kprobing "hash_64.constprop.26"
crashes the system, recursion through get_kprobe?").
