I agree moving this closer to the normal entry path makes sense and the
PMR handling probably belongs there as well. However, I think there are
implications for VHE (the handler runs at EL2 with VBAR_EL2) and for an
event that interrupts a KVM world switch on the hyp vectors. I need to
dig some more into this.

In the meantime, I queued Kiryl's two patches, they're small enough for
stable. Any entry.S rework can come on top of them for future kernels.

Thanks.
