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?
