From 065909b91581cf2438d901a7811a82af3476bdab Mon Sep 17 00:00:00 2001 From: Russell King <rmk@dyn-67.arm.linux.org.uk> Date: Wed, 4 Jan 2006 15:44:16 +0000 Subject: [PATCH] [ARM] Refine selection of ISA_DMA_API and generic dma.c code ISA_DMA_API tells the rest of the kernel if the ISA DMA API is available. Select this symbol only on machine types which make use of the ISA DMA API. Make building of arch/arm/kernel/dma.c depend on this symbol - if a machine does not support the ISA DMA API, it's pointless building this file.
