This is the second version of the series initially posted at [1].
* From v1:
- Simplified masking in patch #1
- Added a patch dropping PMSWINC_EL0 as a shadow register, though it
is still advertised to userspace for the purpose of backward
compatibility of VM save/restore
- Collected ABs/RBs, with thanks
