the linux compat thingie needs those kern_fooat().

I have NOT implemented a single bit of native syscalls API and when I am
going to do it it will be 100% posix API (minus bugs ;) )

we can commit this in two phases: 

phase I: kern_fooat() + linux stuff 
phase II: native fbsd syscalls

I hope to resolve all the issues Eric raised over the weekend (hopefully) and
then it only needs a review(er) + a commiter

I definitely want this in for 7.0R. 

does this sound good to you?
