Subject: [PATCH v1 0/2] RISC-V: enable rust

After the authorship debacle on the RFC, I've tried to be even more
careful this time around. Gary opted for a Co-developed-by in the replies
of the RFC stuff, so I have given them one.
I have added SoB's too, but if that is not okay Gary, then please scream
loudly.

As this is lifted from the state of the Rust-for-Linux tree, the commit
messages from there cannot be preserved, so these patches have commit
messages that I wrote.

I've tested this on Icicle, and the modules seem to work as expected.
Unfortunately there appear to be implicit 32-bit divisions (or similar)
in core Rust code, so, as in the downstream Rust-for-Linux tree, Rust is
only enabled for 64-bit.

Thanks,
Conor.

Changes in v1:
- rebase on v6.3-rc1
- resort the `um` entry in the arch-support table while adding RISC-V
  to it
- drop 32-bit bits
- have another crack at assigning authorship

Changes in RFC-RESEND:
- fix the asymmetrical additions in the Makefile bits
- add cc-cover to my git send-email command...
