Subject: [PATCH v7 03/11] hugetlb: Introduce generic version of set_huge_pte_at
Date: Thu, 20 Sep 2018 06:03:50 +0000	[thread overview]
Message-ID: <20180920060358.16606-4-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>

arm, ia64, mips, powerpc, sh, x86 architectures use the
same version of set_huge_pte_at, so move this generic
implementation into asm-generic/hugetlb.h.
