This series serves a few purposes: - Complete the S1PIE support to include EL2 - Sneak in the EL2 system register world switch As this is a parallel series to the one implementing Address Translation, the S1PIE part of AT is not in any of the two. Depending on which series goes in first, I'll add whatever is needed on top. As mentioned in few of the patches, this implementation relies on a very recent fix to the architecture (D22677 in [1]).
