Well, it's very difficult to say as some of the things involved are
tighly related to the way the linux MM works, what is safe to do and
what is not, what need spinlocking and what not, and so far, I've not
found anything like the beginning of a documentation on that.
On my side, I'm reading the source, trying to understand, and see...
I'm a bit out of time now, but later this week-end, I'll try to give you
an overview of what is needed to get MOL kernel module to work properly
on SMP as we already discussed that quite a bit with Samuel.
