The ./smatch_scripts/build_kernel_data.sh command creates the cross
function db.  It takes a while though.  And it's probably better to
run it a few times because every time you run it the call tree chains
get one call longer.  I run it every night against the latest
linux-next.

I don't have an opinion on this.
