From a4d838536c6e5c1807a863c860d9e767d55ba681 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti Date: Fri, 26 Oct 2018 15:08:12 -0700 Subject: hugetlb: introduce generic version of huge_ptep_get_and_clear() arm, ia64, sh, x86 architectures use the same version of huge_ptep_get_and_clear, so move this generic implementation into asm-generic/hugetlb.h.
