This is the next iteration of this series trying to plug some of our
RAS holes (no pun intended...). See [1] for the original series.
Patches on top of kvmarm-6.17.
* From v1 [1]:
- Bunch of patches picked by Oliver (thanks!)
- Added missing SYS_ERXMISC{2,3}_EL1 from the list of handled RAS
registers
- Added some rationale about the advertising of RASv1p1 (Cornelia)
- Picked AB from Catalin (thanks!)
