Paolo, Here's a first set of fixes, most of which has been simmering in -next for some time now. The most important one is a series from Oliver, plugging a (hard to trigger) race that would result in the wrong mapping being established at S2. The rest is a bunch of cleanups and HW workarounds (the usual Apple vgic issue that keeps cropping up on new SoCs). Please pull, M.
