Yeah, you are right. As this was my first clone of linux-next, hence I've to
spend sometime in configuration and then the whole kernel compilation. But later
I'd like to be able to just build that particular subsystem or the module.
Looking at the top level Makefile, it seems that I should be able to do so.

# cd linux-next
# make mm < --- should work, right ?
