Hello Rick,

may I kindly ping you regarding this patch (patchwork entry at
http://patchwork.ozlabs.org/patch/1083725/)?  It would be great
if you could commit it soonish as without it the qemu RV32 target
is currently non-functional.

The patch has received two reviews and a tested-by and doesn't
touch any generic code, so it should be safe to apply.
