Subject: [PATCH RFC 0/1] Support unknown NMI based on SSE

This patch is based on the SSE features by Clément Léger:
https://lore.kernel.org/all/20250908181717.1997461-1-cleger@rivosinc.com/

It mainly adds support for unknown NMI functionality. Since extension
development has not yet been implemented in SBI, an RFC version is
submitted first.
