Small nit, just writing:
#define has_transparent_hugepage
ought to be enough, right?
In any case:

Another nit, this:

Looks a bit more structured as:
#ifndef has_transparent_hugepage
# ifdef CONFIG_TRANSPARENT_HUGEPAGE
# define has_transparent_hugepage() 1
# else
# define has_transparent_hugepage() 0
# endif
#endif
BYMMV.
