You're claiming copyright on dwarf definitions? ;-)

I'm thinking only Oracle was daft enough to think stuff like that was
copyrightable.

Also; I think it would be very good to not use/depend on DWARF for this.

You really don't need all of DWARF; I'm thikning you only need a few
types; for location we already have regs_get_kernel_argument() which
has all the logic to find the n-th argument.
