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.

From: Dayeol Lee <dayeol@berkeley.edu>
pmp_read_cfg() returns 8-bit value, which is combined together to form a single pmpcfg CSR.
The default promotion rules will result in an integer here ("i*8" is integer, which
flows through) resulting in a 32-bit signed value on most hosts.
That's bogus on RV64I, with the high bits of the CSR being wrong.

Alistair has been contributing to the RISC-V QEMU port for a while now
so I'd like him to be officially listed as a maintainer. I've checked
with the other RISC-V maintainers and there are no objections, and I've
also checked with Alistair so he knows I'm volunteering him.
