mm: skip memory block registration for ZONE_DEVICE
Prevent userspace from trying and failing to online ZONE_DEVICE pages which are meant to never be onlined. For example on platforms with a udev rule like the following: SUBSYSTEM=="memory", ACTION=="add", ATTR{state}=="offline", ATTR{state}="online" ...will generate futile attempts to online the ZONE_DEVICE sections. Example kernel messages: Built 1 zonelists in Node order, mobility grouping on. Total pages: 1004747 Policy zone: Normal online_pages [mem 0x248000000-0x24fffffff] failed Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
