I'll look at what I did to make sure I didn't make an unwanted rcu change. 
>From Paul's talk it looks like there is a bit of a merger of a couple 
of rcu types to keep developers from getting confused and I think the 
unknown functions (that used to be known) should now call the non _bh 
version.

For the network include file I didn't include it any more. The correct 
fix is probably an ifdef based on kernel version or something like 
that.

So it might be useful to look at the changes I did, but I would be wary 
of committing them as is. It'll take me maybe an hour to double check 
and try it again on another system.
