Subject: RFC: deprecate CONFIG_X86_CPU_DEBUG and schedule it for rapid removal

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.
