[PATCH v2 0/5] Support kexec_file on 32-bit RISC-V

This rolled itself back to the top of my inbox, so I figured I'd send it
again as Rob's review landed.  IMO the security/integrity/ima/ change is
sufficiently trivial that it's fine to take it through the RISC-V tree
but I don't have an Review/Ack so I'll wait until this loops back again
to give the security/integrity/ folks a chance to chime in.

If this loops back to the top of my queue (which looks about a month
deep right now) without any comments then I'll put it in riscv/for-next.

Thanks!
