Name: kallsyms in proc
Author: Rusty Russell
Status: Tested on 2.5.67-bk5

D: This adds a /proc/kallsyms if you have CONFIG_KALLSYMS in your
D: kernel. The output is nm-like, with symbols in caps (global) if
D: exported using EXPORT_SYMBOL, rather than the normal static
D: vs. non-static differntiation.
