Indeed, I could swear that I put '#define pmd_huge(x) 0' in that commit log, but it is not there. The string was even still highlighted in my editor. At this point I blame the 'git commit' command for erasing that line.
The other huge page constants in the if(pmd_huge()) block are likewise defined, so we can get rid of the #ifdef CONFIG_HUGETLB_PAGE an let the compiler optimize this block away instead. Doing this the code has a much cleaner appearance.Signed-off-by: David Daney<email@example.com>WBR, Sergei
