This is missing the kexec maintainers, who I've added. I'm happy to
just take this along with the rest of the patch set, as that's probably
easiest. I usually like to get an Ack on this sort of thing, but I'm
just going to speculate that this isn't controversial and put this on
riscv/for-next. LMK if you want me to do something more complicated
like a shared tag, but I see the arm64 stuff went in via the arm64 tree
so I'm assuming this is fine.

Thanks!
