[PATCH v4] memory-hotplug: Fix kernel warning during memory hotplug on ppc64

2016-01-06 Thread John Allen
This patch fixes a bug where a kernel warning is triggered when performing a memory hotplug on ppc64. This warning may also occur on any architecture that uses the memory_probe_store interface. WARNING: at drivers/base/memory.c:200 CPU: 9 PID: 13042 Comm: systemd-udevd Not tainted
