From 2d28a2275c21d04290cfba1555c89a806d2b7706 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 8 Oct 2012 16:32:59 -0700 Subject: [PATCH] mm: thp: fix the pmd_clear() arguments in pmdp_get_and_clear() The CONFIG_TRANSPARENT_HUGEPAGE implementation of pmdp_get_and_clear() calls pmd_clear() with 3 arguments instead of 1. This happens only for !__HAVE_ARCH_PMDP_GET_AND_CLEAR which doesn't seem to happen because x86 defines this and it uses pmd_update.
