It may be too general for a naming. But I don't mind just
selecting CONFIG_RCU_NOCBS_ALL unconditionally. It's easily
changed in the future if anybody complains.

Btw, if CONFIG_RCU_NOCBS_ALL is set, the rcu_nocbs= parameter
is ignored, right? If you want to keep that direction and not
override the Kconfig choice, may be warn the user about that
if the boot parameter is passed?

Thanks.
