hey all,

Can someone tell me if there is a good trick for making
compilations of kernel diffs? Just a command which compares two kernel
trees and only includes the neccesary files to patch from one to another.
It seems there should be some sort of utility for doing it, (knowing to
ignore *.o and .config and .depend, etc) but i haven't been able to find
one. diff(1) -r doesn't seem to be working too well for this. Thanks,
