Subject: [PATCH V3 2/2] x86/mm: use min instead of min_t
Date: Wed, 10 Dec 2014 10:09:03 +0800 [thread overview]
Message-ID: <5487AB3F.7050807@huawei.com> (raw)
The type of "MAX_DMA_PFN" and "xXx_pfn" are both unsigned long now, so use
min() instead of min_t().
Signed-off-by: Xishi Qiu <qiuxishi@huawei.com>
Suggested-by: Andrew Morton <akpm@linux-foundation.org>
