Subject: [PATCH 2/5] ARM: make dma_addr_t 64-bit on LPAE
Date: Mon,  5 Aug 2013 17:50:06 -0500	[thread overview]
Message-ID: <1375743009-28972-2-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1375743009-28972-1-git-send-email-robherring2@gmail.com>

From: Rob Herring <rob.herring@calxeda.com>

LPAE systems may have 64-bit capable DMA, so dma_addr_t needs to be
64-bit.
