mm/demotion: expose memory tier details via sysfs
Add /sys/devices/virtual/memory_tiering/ where all memory tier related
details can be found. All allocated memory tiers will be listed there as
/sys/devices/virtual/memory_tiering/memory_tierN/
The nodes which are part of a specific memory tier can be listed via
/sys/devices/virtual/memory_tiering/memory_tierN/nodes
A directory hierarchy looks like
:/sys/devices/virtual/memory_tiering$ tree memory_tier4/
memory_tier4/
├── nodes
├── subsystem -> ../../../../bus/memory_tiering
└── uevent
:/sys/devices/virtual/memory_tiering$ cat memory_tier4/nodes
0,2
[[email protected]: drop toptier_nodes from sysfs]
