Subject: [PATCH 116/208] x86/fpu: Simplify fpu__cpu_init()
Date: Tue,  5 May 2015 19:50:08 +0200	[thread overview]
Message-ID: <1430848300-27877-38-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1430848300-27877-1-git-send-email-mingo@kernel.org>

After the latest round of cleanups, fpu__cpu_init() has become
a simple call to fpu__init_cpu().

Rename fpu__init_cpu() to fpu__cpu_init() and remove the
extra layer.
