From 3e761a42e19c63b624ebac94d918d8a15e07e2a7 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Mon, 27 Feb 2017 14:30:25 -0800 Subject: [PATCH] mm, x86: fix HIGHMEM64 && PARAVIRT build config for native_pud_clear() Looks like I also missed the build config that includes CONFIG_HIGHMEM64G && CONFIG_PARAVIRT to export the native_pud_clear() dummy function.
