Hi Kamil, Maxime, I haven't managed to reserve time to review this, sorry for that. I hope others can chime in before I do. Would any of you be willing to be included as maintainer of the new code on MAINTAINERS?

I don't see the new files (accel/stubs/nvmm-stub.c, include/sysemu/nvmm.h, target/i386/nvmm-all.c) being added to MAINTAINERS. Can you add it as a follow up patch?
