If you had a distro kernel before (like a default RedHat) and then you
download kernel.org source and compiled from that, then you most likely will
have a number of "distro" applied patches missing and hence missing
directories/files when doing a comparison. If this is the case download your
distro supplied kernel files and follow Matt's instructions.

This may or may not be your problem and again Matt's advice is probably the
solution you are after.
