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@xxxxxxx>
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.
