I think this patch needs an additional bit for Documentation/ABI
(might be other parts of /sys/devices/system/memory missing from
there).

Also, I wonder if it might not make more sense to use a symlink here? That is

/sys/devices/system/memory/memoryX/node -> /sys/devices/system/node/nodeY ?

And then we could, potentially, have symlinks returning from the node
side to indicate all memory sections on that node (might be handy for
node offline?):

/sys/devices/system/node/nodeX/memory1 -> /sys/devices/system/memory/memoryY
/sys/devices/system/node/nodeX/memory2 -> /sys/devices/system/memory/memoryZ

Dunno, the latter probably should be a separate patch, but does seem
more like the sysfs behavior (and the number (node or memory section)
should be easily obtained from the symlinks via readlink, as opposed
to cat with the current patch?).

Thanks,
Nish
