Subject: [PATCH 05/11] x86: Change get_max_mapped() to inline
Date: Mon, 7 Feb 2011 15:17:06 -0800 [thread overview]
Message-ID: <1297120632-24933-6-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1297120632-24933-1-git-send-email-yinghai@kernel.org>
Move it into head file. to prepare use it in other files.
-v2: hpa pointed out that u64 should not be used here.
Actually We could unsigned long here. because for 32bit it will under 4g.
