Yasunori Goto 718127cc31 [PATCH] wait_table and zonelist initializing for memory hotadd: add return code for init_current_empty_zone
When add_zone() is called against empty zone (not populated zone), we have to
initialize the zone which didn't initialize at boot time.  But,
init_currently_empty_zone() may fail due to allocation of wait table.  So,
this patch is to catch its error code.

Changes against wait_table is in the next patch.
