From 2a7326b5bbafac4c96bcdb944b2a773593030b96 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 17 Jul 2007 04:03:37 -0700 Subject: CONFIG_BOUNCE to avoid useless inclusion of bounce buffer logic The bounce buffer logic is included on systems that do not need it. If a system does not have zones like ZONE_DMA and ZONE_HIGHMEM that can lead to the use of bounce buffers then there is no need to reserve memory pools etc etc. This is true f.e. for SGI Altix. Also nicifies the Makefile and gets rid of the tricky "and" there.
