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.

Thanks for starting the efforts; this is really needed if we want the 
infrastructure to be used also by someone else than its developers :)

+7. Limitations
+==============

Miroslav Benes, who is working on creating the actual patches we are 
shipping for our kernels, should already have a decent cheat-sheet 
regarding things that the patch author should be extra careful when 
creating a patch (inlining and other gcc optimizations such as isra, 
functions that use switch_to(), percpu, ...).

I am not really sure whether these should go to limitations, or maybe 
they'd better be placed into a separate chapter, but I'd really like to 
see it included.

Thanks,
