Subject: Re: [PATCH v4 0/9] latched RB-trees and __module_address()

For the record I still think it's better to just look it up in the
kernel page tables, which already maintain that information. This is a much
simpler, much less risky patch. It works on all architectures that use page
tables for the kernel, and have a X bit in them. The rest are likely
obscure and won't have a lot of modules.

My patch implementing this for x86 is here:
