Subject: [PATCH 1/4] x86/mm: delete disabled debug code

This code doesn't run. Since 2008 the kernel has gained more flexible
logging and tracing capabilities; presumably if anyone wanted to take
advantage of this log message they would have got rid of the
"if (0)" so they could use these capabilities.

Since they haven't, just delete it.
