Turns out this urgent boot fix got undone in the merge somehow.
Maybe just reapply it? The following should do it with some fuzz:

$ git show 626479696d2 | patch -p1

Or let me know if you want me to send you a patch.

Then in addition to the above, I'm also seeing a regression with commit
8a965b3b (mm, slab_common: Fix bootstrap creation of kmalloc caches),
but it seems to be related to some kconfig option. Seeing it on at least
omap and vexpress, I'll post more info on that once I've tracked it down:
