Subject: [PATCH 7/9] x86/microcode/intel: Unexport save_mc_for_early()
Date: Mon, 6 Jun 2016 17:10:48 +0200 [thread overview]
Message-ID: <1465225850-7352-8-git-send-email-bp@alien8.de> (raw)
In-Reply-To: <1465225850-7352-1-git-send-email-bp@alien8.de>
From: Borislav Petkov <bp@suse.de>
It is used only in intel.c, drop the CONFIG_HOTPLUG_CPU ifdeffery from
the header and turn it into a void function because its return value
wasn't being used anyway.
No functionality change.
Signed-off-by: Borislav Petkov <bp@suse.de>
