Subject: [PATCH 1/3] 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.

+Specify \fIZONE\fP as the name of a memory zone, as shown in the output of the
+\fBlsmem -o +ZONES\fP command. The output shows one or more valid memory zones
+for each memory range. If multiple zones are shown, then the memory range

+to the zone Movable, if this is among the valid zones. This default can be
+changed by specifying the \fB--zone\fP option with another valid zone.
+For memory ballooning, it is recommended to select the zone Movable for memory
+online and offline, if possible. Memory in this zone is much more likely to be
+able to be offlined again, but it cannot be used for arbitrary kernel

From: Gerald Schaefer <gerald.schaefer@de.ibm.com>

Subject: [PATCH 2/3] tests/lsmem: update lsmem test with ZONES column
The existing s390 and x86_64 dumps already contain the valid_zones sysfs
attribute, so just add a new "lsmem -o +ZONES" test command and update
the expected results.
