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().
Regards,
-Kame
