The probe plugin requires access to the source code for some operations.
The source code must be in the exact same location as specified by the
DWARF tags, but sometimes the location is an absolute path that cannot
be replicated by a normal user. This change adds the -s|--source option
to allow the user to specify the root of the kernel source tree.

Thanks, I saw it but didn't manage to test it yet, will try probably
tomorrow.

Really cool stuff, thanks for your patch and to Masami for his amazing work on
'perf probe'.
I think we should look at usual places like debuginfo packages and
/usr/src/linux-`uname`, ~/git/linux-2.6/, etc, but that is something for a
follow on patch.
Best Regards,
