From b9d9d6911bd5c370ad4b3aa57d758c093d17aed5 Mon Sep 17 00:00:00 2001
From: Thomas Gleixner <tglx@linutronix.de>
Date: Mon, 26 Dec 2016 22:58:19 +0100
Subject: [PATCH 2/3] smp/hotplug: Undo tglxs brainfart
The attempt to prevent overwriting an active state resulted in a
disaster which effectively disables all dynamically allocated hotplug
states.
Cleanup the mess.
Fixes: dc280d936239 ("cpu/hotplug: Prevent overwriting of callbacks")

Subject: [PATCH 3/3] x86/mce/AMD: Make the init code more robust
If mce_device_init() fails then the mce device pointer is NULL and the
AMD mce code happily dereferences it.
