Subject: [PATCH v2 06/27] ARM: change dma_alloc/free_coherent to match other architectures
Date: Thu,  5 Mar 2015 22:49:59 +0100	[thread overview]
Message-ID: <1425592221-23774-9-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1425592221-23774-1-git-send-email-dev@lynxeye.de>

As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM
we define DMA_ADDRESS_BROKEN to mark them. In order to use them on
other architectures with a different mapping they need proper fixing.
