Subject: [RFC PATCH] arm: dma-mapping: fallback allocation for cma failure
Date: Tue, 20 May 2014 14:57:47 +0900	[thread overview]
Message-ID: <537AEEDB.2000001@lge.com> (raw)


Thanks for your advise, Michal Nazarewicz.

Having discuss with Joonsoo, I'm adding fallback allocation after __alloc_from_contiguous().
The fallback allocation works if CMA kernel options is turned on but CMA size is zero.
