I see less maintainer tags for the parts that touch other ports than I would feel comfortable merging. I'm going to let this sit in my inbox for a bit and we'll see if anything collects. For patch sets I submit that clean up other ports I've attempted to split the patch into N patch sets, where: * One part adds the generic support, which starts out as dead code. * One part per arch uses the generic support. This is a bit of a headache, but it at least allows us to get the RISC-V version that uses the generic support in quickly while waiting on acks from the other arch maintainers. Like I said, I'll wait a bit and hope people ack. Thanks!
