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!

Add RISC-V to the list of supported kexec architecturs, we need to add the definition early-on so that later patches can use it.
