Subject: [PATCH v7 06/11] hugetlb: Introduce generic version of huge_pte_none
Date: Thu, 20 Sep 2018 06:03:53 +0000	[thread overview]
Message-ID: <20180920060358.16606-7-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>

arm, arm64, ia64, mips, parisc, powerpc, sh, sparc, x86 architectures
use the same version of huge_pte_none, so move this generic
implementation into asm-generic/hugetlb.h.
