From e9da6e9905e639b0f842a244bc770b48ad0523e9 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Mon, 30 Jul 2012 09:11:33 +0200 Subject: ARM: dma-mapping: remove custom consistent dma region This patch changes dma-mapping subsystem to use generic vmalloc areas for all consistent dma allocations. This increases the total size limit of the consistent allocations and removes platform hacks and a lot of duplicated code. Atomic allocations are served from special pool preallocated on boot, because vmalloc areas cannot be reliably created in atomic context.
