[PATCH 0/5] io-pgtable fixes + ARM short-descriptor format

[Robin Murphy <robin.murphy-5wv7dgnIgG8@public.gmane.org>]

This has been tested on an MMU-500 Fast Model, with the ARM SMMU driver
hacked up to force short-descriptor at stage 1 - doing it properly needs
more work to decouple the context format from the kernel bit-ness. Since
I didn't want to delay getting this lot posted, that can come later.

Thanks,
Robin.
