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.
