Hey Eric,

Thanks for the patches!

Unfortunately there is already a series "target/riscv: Update QEmu for
Zb[abcs] 1.0.0"
(https://www.mail-archive.com/qemu-devel@nongnu.org/msg839086.html)
that adds support for the v1.0.0 bit manip extension. That has been
reviewed and queued to be merged.

If you have fixes or features that apply on top of that please send
them though :)
