[akpm]

The patch titled
     optional ZONE_DMA: introduce CONFIG_ZONE_DMA
has been removed from the -mm tree.  Its filename was
     introduce-config_zone_dma.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: optional ZONE_DMA: introduce CONFIG_ZONE_DMA
From: Christoph Lameter <clameter@sgi.com>

This patch simply defines CONFIG_ZONE_DMA for all arches.  We later do special
things with CONFIG_ZONE_DMA after the VM and an arch are prepared to work
without ZONE_DMA.

CONFIG_ZONE_DMA can be defined in two ways depending on how an architecture
handles ISA DMA.

First if CONFIG_GENERIC_ISA_DMA is set by the arch then we know that the arch
needs ZONE_DMA because ISA DMA devices are supported.  We can catch this in
mm/Kconfig and do not need to modify arch code.

Second, arches may use ZONE_DMA in an unknown way.  We set CONFIG_ZONE_DMA for
all arches that do not set CONFIG_GENERIC_ISA_DMA in order to insure backwards
compatibility.  The arches may later undefine ZONE_DMA if their arch code has
been verified to not depend on ZONE_DMA.
