Not a concern for now. > The problem seems to be related to dependencies. It is addressed upstream with commit 2b800f7c0c6c ("powerpc/cell: Drop select of MEMORY_HOTPLUG"). After this patch is applied, MEMORY_HOTPLUG is no longer enabled with powerpc:defconfig, and the problem is no longer seen. Copying Michael to see if there is any concern about having this patch applied to v4.9.y. Guenter
