I am not sure this list is complete. @ved-rivos can you remind us which other extensions can throw page-fault exceptions when there is no MMU? Are all of the problematic extensions ones that Spike doesn't support yet?

Besides Sv* extensions, the only other extension that can produce a page fault without MMU is SPMP. I believe SPMP is not implemented in spike yet. |

Thanks, @ved-rivos. I think we can proceed with this PR as-is.

@chihminchao it looks like the CI failures are unrelated to the code change. Let me know if you need me to retry CI in a few hours. |
