This is creepy.  I was able to reproduce the oops here with your
configuration file and making buffers for kallsyms static solved the
problem.  It isn't stack overflow.  At maximum those arrays added 254
bytes to the stack and when the oops occurs stack area was left more
than enough.  I'll keep looking into why that happened but the attached
patch should get us going on the original subject.

Thanks.
