LivePatch framework deserves some documentation, definitely.
This is an attempt to provide some basic info. I hope that
it will be useful for both LivePatch producers and also
potential developers of the framework itself.

additional issues. With Chris', Balbir's and Josh's comments taken

To uncouple the livepatch code from module loader internals move a
slightly refactored version of klp_find_object_module to module.c
This allows to mark find_module static and removes one of the last
users of module_mutex outside of module.c.
