CONFIG_X86_CPU_DEBUG really seems to be causing more problems than it ever solved. This is an RFC for immediately deprecating it, and schedule it for removal in the 2.6.34 cycle. If this was a high value feature, it would be different -- but it's not even close. Posting this as an RFC just on the offchance someone actually depends on this. -hpa -- H.
