From cae72abc1af0c1ef4cb39e7187c5af44a7ce17a4 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti Date: Fri, 26 Oct 2018 15:08:22 -0700 Subject: [PATCH] hugetlb: introduce generic version of huge_pte_none() 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.
