OK, I am dropping the slub/slab patch from the queue for now. Here's
what I am going to push to Linus:

http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=shortlog;h=topic/slab/earlyboot

So I am sending the GFP_NOWAIT conversion for boot code even though you
didn't seem to like it (but didn't explicitly NAK) as it fixes problems
on x86.
