Subject: [PATCH v2 0/3] powerpc/mm: movable hotplug memory nodes
These changes enable onlining memory into ZONE_MOVABLE on power, and the
creation of discrete nodes of movable memory.
We provide a way to describe the extents and numa associativity of such
a node in the device tree, yet still defer the memory addition to take
place post-boot through hotplug.
In v1, this patchset introduced a new dt compatible id to explicitly
create a memoryless node at boot. Here, things have been simplified to
be applicable regardless of the status of node hotplug on power. We
still intend to enable hotadding a pgdat, but that's now untangled as a
separate topic.
v2:
* Use the "status" property of standard dt memory nodes instead of
introducing a new "ibm,hotplug-aperture" compatible id.
* Remove the patch which explicitly creates a memoryless node. This set
no longer has any bearing on whether the pgdat is created at boot or
at the time of memory addition.
v1:
* http://lkml.kernel.org/r/1470680843-28702-1-git-send-email-arbab@linux.vnet.ibm.com
