Subject: [PATCH 14/26] x86/oprofile: Moving nmi_setup_cpu_mux() in nmi_int.c
Date: Tue, 28 Jul 2009 19:07:14 +0200 [thread overview]
Message-ID: <1248800846-25422-15-git-send-email-robert.richter@amd.com> (raw)
In-Reply-To: <1248800846-25422-1-git-send-email-robert.richter@amd.com>
This patch moves some code in nmi_int.c to get a single separate
multiplexing code section.
