Grumble. Any chance we could add an kmem_cache option which requires
the memory to be aligned? Otherwise we could rewrite our own sub-page
allocator in ext4 that only handled aligned filesystem block sizes
(i.e., 1k, 2k, 4k, etc.) but that would be really silly and be extra
code that really should be done once at core functionality.
