lsmem/chmem: add memory zone awareness
With this patch, valid memory zones can be shown with lsmem, and chmem can
set memory online/offline in a specific memory zone, if allowed by the
kernel. The valid memory zones are read from the "valid_zones" sysfs
attribute, and setting memory online to a specific zone is done by
echoing "online_kernel" or "online_movable" to the "state" sysfs
attribute, in addition to the previous "online".
This patch also changes the default behavior of chmem, when setting memory
online without specifying a memory zone. If valid, memory will be set
online to the zone Movable. This zone is preferable for memory hotplug, as
it makes memory offline much more likely to succeed.
