Check out all the cacheline_aligned usage, in all the cases I could see
there was no reason to do this on a UP machine. You could probably get
away with redefining them to do nothing.

Also you could drop the sizes of the hashes (dentry, inode, mount,
buffer, page, route) if they are taking up RAM.
