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.
