The patch also adds a kernel command line option. That should be mentioned in the patch description and documented in Documentation/kernel-parameters.txt. Also, I'd like you to choose a better name for the kernel command line option than "cmma", which is completely opaque to me -- it doesn't seem to be the name or even the initials of anything in the patch. Presumably it's somehow related to CMO, but just how is not at all clear.
