Hi Sam,

Thanks a lot for this work and sorry for the delay.

This should read ".tmp_vmlinux3". Also, how about storing these two
variables in the kallsyms() function instead? That way, you have the
assignment in one place only and this block becomes a little simpler.

This was the only error I spotted, it looks fine otherwise. Please
resubmit with the above typo fixed (whether or not you move the variable
assignments I leave up to you) and I'll add it to linux-next.

Thanks,
Michal
