Ah, I see. The naming starts to get really confusing. Could you please =
give this a slightly better name, such as CONFIG_KVM_BOOK3S_PR_POSSIBLE =
or such, so that it's obvious that this #ifdef doesn't mean "option is =
enabled", but instead means "option can potentially be enabled through a =
module".
