See "kallsyms_lookup_name" in include/linux/kallsyms.h (implemented in
kernel/kallsyms.c).
Beware:
- CONFIG_KALLSYMS might be undefined. In that case it always returns 0
- the function returns the address of *any* known symbol, not just
functions (this can be easily improved to also return the symbol type)
- the function is extremely inefficient, as it does a linear search
over all the symbols. kallsyms is optimized to work the other way
around: get the name from the address.

It is a mistake to think you can solve any major problems
just with potatoes.
