SLAB_FREELIST_RANDOM is default n, so this patchset won't get much
runtime testing.

How about you cook up a (-mm only) patch which makes the kernel default
to SLAB_FREELIST_RANDOM=y, SHUFFLE_PAGE_ALLOCATOR=y (or whatever) to
ensure we get a decent amount of runtime testing?  Then I can hold that
in -mm (and -next) until we get bored of it?
