Hi Michael,

I'm working an adding support for ppc64 to leaking_addresses.pl, I've
added the kernel address regular expression that you suggested. I'd like
to add the false positive for vsyscall addresses. Excuse my ignorance
but does PowerPC use a constant address range for vsyscall like x86_64
does? The ppc64 machine I have access to does not output anything for

$ cat /proc/PID/tasks/PID/smaps or
$ cat /proc/PID/tasks/PID/maps

thanks,
Tobin.
