Here's the first bunch of patches of 5-level patchset. Let's see if I'm on right track addressing Ingo's feedback. :) These patches prepare x86 code to be switched from <asm-generic/5level-fixup> to <asm-generic/pgtable-nop4d.h>. It's a stepping stone for adding 5-level paging support. Please review and consider applying. Kirill A.
