Sorry..this can be a workaround but I noticed I miss something..

ok, just use N_HIGH_MEMORY here and add comment for hotplugging support is not yet.

Christoph-san, Lee-san, could you confirm following ?

- when SLAB is used, kmalloc_node() against offline node will success.
- when SLUB is used, kmalloc_node() against offline node will panic.

Then, the caller should take care that node is online before kmalloc().
