applied to tip/x86/pat, thanks Andreas. (i presume you'll send a 
followup patch for the suggestions that came up in the discussion)

#5 makes sense too, but it didnt apply cleanly:

 Applying patch 
 patches/pat-x86-pat-make-pat-x-mtrr-type-more-readable.patch
 patching file arch/x86/mm/pat.c
 Hunk #1 FAILED at 185.
 1 out of 1 hunk FAILED -- rejects in file arch/x86/mm/pat.c

(it didnt apply neither against tip/x86/pat or tip/master, nor against 
linus/master. I guess it's some mixup somewhere.)
