Hi all,

Simple, untested patch. Any objections?

Cheers,
Rusty.

Name: Include All Functions in kallsyms
Author: Rusty Russell
Status: Experimental

D: Do not discard functions outside _stext and _etext, but include all
D: 't' or 'T' functions. This means __init functions are included (in my
D: config this means an increas from 5691 to 6442 functions.
D:
D: TODO: Allow multiple kallsym tables, discard init one after init.
D: TODO: Use huffman name compression and 16-bit offsets (see IDE
D: oopser patch)
