Hi,

In this version we have a change in patch 11. We're now firing a
GUEST_ERROR if write_misa() fails and we need to rollback (i.e. not
change MISA ext).

No other changes made. 

Changes from v8:
- patch 11:
  - log a GUEST_ERROR if we decided to keep the current env->misa_ext
    value because the user value failed our validation
- v8 link: https://lists.gnu.org/archive/html/qemu-devel/2023-04/msg03584.html
