Please refer to:

Now, Yinghai has tried to allocate pagetables and vmemmap pages in local

exclude the pagetables and vmemmap pages.
So we need the following sequence:
1) Parse SRAT, store numa_meminfo.
2) Initialize memory mapping, allocate
Since we have introduced hotplug info into struct numa_meminfo, we need

memory on other nodes.
This patch modifies
In order to support allocating pagetable and vmammap pages in local node,
we should initialzie memory mapping without any limitation for memblock first,
using memblock to reserve pagetable and vmemmap pages in local node, and then

In this way, we
Since we are using struct numa_meminfo to store SRAT info, and sanitize

calculate zone_movable_pfn[] with the limit from zone_movable_limit[].

When implementing movablemem_map boot option, we introduced an array
movablemem_map.map[] to store the memory ranges to be set as ZONE_MOVABLE.
Since ZONE_MOVABLE is the latst zone of a node, if user didn't specify
the whole node memory range, we need to extend it to the node end so that
we can
Ensure memblock will not allocate memory from areas that may be
ZONE_MOVABLE. The map info is from movablemem_map boot option.
The following problem was reported by Stephen Rothwell:
The definition of struct movablecore_map is protected by
CONFIG_HAVE_MEMBLOCK_NODE_MAP but its use in
Add functions to parse movablemem_map boot option. Since the option
could be specified more then once, all the maps will be stored in the
global array movablemem_map.map[].
And also, we keep the array in monotonic increasing order by start_pfn.
And merge all overlapped ranges.
Signed-off-by:
Since node info in SRAT may not be in increasing order, we may meet
a lower range after we handled a higher range. So we need to keep
the lowest movable pfn each time we parse a SRAT memory entry, and
update it when we get a lower one.
This patch introduces a new array zone_movable_limit[], which
This patch-set introduces a new boot option movablemem_map.
The functionality will be posted in two parts:
part1: Implement movablemem_map logic.
In this part, pagetable and vmemmap are not allowed to be allocated
on local node.
part2: Support allocating pagetable and vmemmap on
The Hot Pluggable field in SRAT points out if the memory could be
hotplugged while the system is running. It is useful to print out
this info when parsing SRAT.

The netlink_diag can be built as a module, just like it's done in
unix sockets.
The core dumping message carries the basic info about netlink sockets:
family, type and protocol, portis, dst_group, dst_portid, state.
Groups can be received as an optional parameter NETLINK_DIAG_GROUPS.
