    Subject[PATCH v4 01/11] hugetlb: Harmonize hugetlb.h arch specific defines with pgtable.h
    Date
    asm-generic/hugetlb.h proposes generic implementations of hugetlb
    related functions: use __HAVE_ARCH_HUGE* defines in order to make arch
    specific implementations of hugetlb functions consistent with pgtable.h
    scheme.
