[PATCH] mm: remove PG_highmem
Remove PG_highmem, to save a page flag. Use is_highmem() instead. It'll generate a little more code, but we don't use PageHigheMem() in many places. Signed-off-by: Badari Pulavarty <pbadari@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
