Well, "mm: use irq locking suffix instead local_irq_disable()" is a
fairly straightforward cleanup series, so it would be best to base your
patches on that work, please.

There is a significant review comment from Vladimir against "mm:
list_lru: add lock_irq member to __list_lru_init()" to which Sebastian
has yet to respond (please).

It looks like they're ready for an initial merge.
