used by kernel, and Linux cannot migrate pages used by kernel.
So we need a way to specify hotpluggable memory as movable. It
should be as easy as possible.

Since we modify movablecore boot option to support

We reserved hotpluggable memory in memblock. And when memory initialization
is done, we have to free it to buddy system.
This patch free memory reserved by memblock with flag MEMBLK_HOTPLUGGABLE.

If all the memory ranges in SRAT are hotpluggable, we should not
arrange them all in ZONE_MOVABLE. Otherwise the kernel won't have
enough memory to boot.
This patch introduce a global variable kernel_nodemask to mark
all the nodes the kernel resides in. And no matter if they are
hotpluggable, we
Since Yinghai has implement Allocate pagetable pages in local node, for a
node with hotpluggable memory, we have to allocate pagetable pages first, and
then reserve the rest as hotpluggable memory in memblock.

There is no flag in memblock to discribe what type the memory is.
Sometimes, we may use memblock to reserve some memory for special usage.
For example, as Yinghai did in his patch, allocate pagetables on local
node before all the memory on the node is mapped.
Please refer to Yinghai's patch:

If system can create movable node which all memory of the
node is allocated as ZONE_MOVABLE, setup_node_data() cannot
allocate memory for the node's pg_data_t.
So, use memblock_alloc_try_nid() instead of memblock_alloc_nid()

The Hot-Pluggable Fired in SRAT specified which memory ranges are hotpluggable.
We will arrange hotpluggable memory as ZONE_MOVABLE for users who want to use

So we improve
Arrange hotpluggable memory as ZONE_MOVABLE will cause NUMA performance

For users who don't use memory hotplug and who don't want to lose their NUMA
performance, they need a way to disable this functionality.
So, if users specify
