This is the second in the series of patches to build out an appropriate
kprobes blacklist. This series blacklists system_call() and functions
involved when handling the trap itself. Not everything is covered, but
this is the first set of functions that I have tested with. More
patches to follow once I expand my tests.
I have converted many labels into private -- these are labels that I
felt are not necessary to read stack traces. If any of those are
important to have, please let me know.
