Subject[PATCH v6 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.
