Subject: [PATCH v7 01/11] hugetlb: Harmonize hugetlb.h arch specific defines with pgtable.h
Date: Thu, 20 Sep 2018 06:03:48 +0000	[thread overview]
Message-ID: <20180920060358.16606-2-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>

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.
