Based on the current work of huge TLB, no code is added for THP but info gcc to compile the huge TLB code for THP. That is the second factor why the present bit is selected.

This exact sequence happens many times in the patch.Can we define some symbol (perhaps in page.h) that is set for both of the conditions?
#if defined(CONFIG_HUGETLB_PAGE) || defined(CONFIG_TRANSPARENT_HUGEPAGE) #define BRFL #endif . . . #ifdef BRFL /* everywhere else */ We of course wouldn't use the name BRFL, but rather something fitting.With a change like that, I would like to retest the patches and try to get them merged.
