For architectures like powerpc that support multiple explicit hugepage sizes, HPAGE_SHIFT indicate the default explicit hugepage shift. For THP to work the hugepage size should be same as PMD_SIZE. So use PMD_SHIFT directly. So move the define outside CONFIG_TRANSPARENT_HUGEPAGE #ifdef because we want to use these defines in generic code with if (pmd_trans_huge()) conditional.
