OK, I'll give that a once-over!
So yeah, it is pretty clearly doing what I was (slowly) deducing: PPIs are
getting percpu stuff, and SPI are all getting just this
smp_processor_id() stuff.

Ah, I see. I'll track that commit down. Thanks.

Not yet. I hit the global timer just to get my port going. I needed to
implement and verify our timer block. But I can give the TWD a
