We kept CONFIG_DETECT_SOFTLOCKUP around for compatibility with older configs. But it was enabled by default if CONFIG_DEBUG_KERNEL. So if we want to enable CONFIG_LOCKUP_DETECTOR on configs that had CONFIG_DETECT_SOFTLOCKUP, all we need is to have the same enabling by default if CONFIG_DEBUG_KERNEL. We can then remove CONFIG_DETECT_SOFTLOCKUP directly. So tag CONFIG_LOCKUP_DETECTOR as default y. This is what we want for most serious kernel debugging anyway. And also forbid the lockup detector in S390 as it was for the previous softlockup detector, event though the true reason for that is not outlined.
