From 28aa483f80d146a8f117eb65a4fddf31d58230d7 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 15 May 2007 18:45:49 -0700 Subject: [PATCH] x86: Fix discontigmem + non-HIGHMEM compile It's not necessarily a very sane configuration, but people running "make randconfig" noticed it wouldn't compile. This fixes some obvious problems in discontig.c to allow a clean compile.
