RISC-V Patches for the 3.1 Soft Freeze, Part 2

This tag contains a few simple patches that I'd like to target for the
QEMU soft freeze.  There's only one code change: a fix to our PMP
implementation that avoids an internal truncation while computing a
partial PMP read.

I also have two updates to the MAINTAINERS file: one to add Alistair as
a RISC-V maintainer, and one to add our newly created mailing list.
