Hmm. What is "this"? The revert? That said, I do wonder whether virtualization still has problems with CONFIG_RODATA, though. We limit the RODATA memory ranges based on KPROBES and HOTPLUG_CPU, but not based on VIRTUALIZATION. I'd expect any virtualization fixups to hit the same problems that the SMP alternatives hit. No?
