Subject: [PATCH v7 10/11] hugetlb: Introduce generic version of huge_ptep_set_access_flags
Date: Thu, 20 Sep 2018 06:03:57 +0000	[thread overview]
Message-ID: <20180920060358.16606-11-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>

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

Message-ID: <20180920060358.16606-11-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>

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