From 0b7a96114bd5991d355a1f1c1d3d9c0c9d9c1cfc Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 4 Feb 2008 22:28:33 -0800 Subject: [PATCH] i386: Resolve dependency of asm-i386/pgtable.h on highmem.h pgtable.h does not include highmem.h but uses various constants from highmem.h. We cannot include highmem.h because highmem.h will in turn include many other include files that also depend on pgtable.h So move the definitions from highmem.h into pgtable.h.
