Subject: [PATCH 6/9] staging: ion: Set minimum carveout heap allocation order to PAGE_SHIFT
Date: Fri, 29 Jan 2016 22:07:35 -0800	[thread overview]
Message-ID: <1454134058-16466-7-git-send-email-john.stultz@linaro.org> (raw)
In-Reply-To: <1454134058-16466-1-git-send-email-john.stultz@linaro.org>

From: Rajmal Menariya <rajmal.menariya@spreadtrum.com>

In carveout heap, change minimum allocation order from 12 to
PAGE_SHIFT. After this change each bit in bitmap (genalloc -
General purpose special memory pool) represents one page size
memory.
