Hi,

This new version squashed patches 1 and 2 together and there's more
detail in patch 1 about why we're not violating the spec by keeping
write_misa() as a no-op.

All patches are acked.

Changes from v4:
- patches 1 and 2 from v4: squashed together
- patch 1:
  - added more detail in the commit msg about why a no-op misa write is
    spec compliant
- v4 link: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg04780.html
