Cyrill Gorcunov 41bb3476b3 mm: save soft-dirty bits on file pages ... Andy reported that if file page get reclaimed we lose the soft-dirty bit if it was there, so save _PAGE_BIT_SOFT_DIRTY bit when page address get encoded into pte entry. Thus when #pf happens on such non-present pte we can restore it back.
