Linus Torvalds b5db0e3865 Revert "x86 PAT: remove CPA WARN_ON for zero pte" ...

This reverts commit 58dab916df, which
makes my Nehalem come to a nasty crawling almost-halt.  It looks like it
turns off caching of regular kernel RAM, with the understandable
slowdown of a few orders of magnitude as a result.
