x86: Remove "x86 CPU features in debugfs" (CONFIG_X86_CPU_DEBUG)
CONFIG_X86_CPU_DEBUG, which provides some parsed versions of the x86 CPU configuration via debugfs, has caused boot failures on real hardware. The value of this feature has been marginal at best, as all this information is already available to userspace via generic interfaces. Causes crashes that have not been fixed + minimal utility -> remove. See the referenced LKML thread for more information. Reported-by: Ozan Çağlayan <ozan@pardus.org.tr> Signed-off-by: H.
