Subject: [PATCH] CMA: generalize CMA reserved area management functionality (fixup)
Date: Thu, 17 Jul 2014 11:36:07 +0200	[thread overview]
Message-ID: <1405589767-17513-1-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <53C78ED7.7030002@samsung.com>

MAX_CMA_AREAS is used by other subsystems (i.e. arch/arm/mm/dma-mapping.c),
so we need to provide correct definition even if CMA is disabled.
This patch fixes this issue.
