From: Christoph Lameter Date: Tue, 5 Feb 2008 06:28:33 +0000 (-0800) Subject: i386: Resolve dependency of asm-i386/pgtable.h on highmem.h X-Git-Tag: v2.6.25-rc1~984 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b7a96114bd5991d355a1f1c1d3d9c0c9d9c1cfc;p=linux-2.6 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.
