mm: add node states sysfs class attributeS
Add a per node state sysfs class attribute file to /sys/devices/system/node
to display node state masks.
E.g., on a 4-cell HP ia64 NUMA platform, we have 5 nodes: 4 representing
the actual hardware cells and one memory-only pseudo-node representing a
small amount [512MB] of "hardware interleaved" memory. With this patch, in
/sys/devices/system/node we see:
#ls -1F /sys/devices/system/node
has_cpu
has_normal_memory
node0/
node1/
node2/
node3/
node4/
online
possible
#cat /sys/devices/system/node/possible

#cat /sys/devices/system/node/has_normal_memory

#cat /sys/devices/system/node/has_cpu
