Last Minute RISC-V Patches for 5.6

Sorry for the last minute patches, but a few things fell through the cracks
recently.  I was on the fence about sending a late PR just for the M-mode
fixes, as we don't really have any users, but the last patch fixes the build
for Fedora which I consider pretty important.  Given that the M-mode fixes
should be very low risk, I figured it's worth sending them along as well.

This passes my standard "boot in QEMU" test.
