Subject: [VOYAGER] add prefill_possible_mask() to fix linker breakage


commit 329513a35d1a2b6b28d54f5c2c0dde4face8200b
Author: Yinghai Lu <>

    x86: move prefill_possible_map calling early

prefill_possible_mask() was hidden under CONFIG_HOTPLUG_CPU rendering
it invisitble to voyager.  Since this commit it's exposed, but not
provided by the voyager subarch, so add a dummy stub to fix the link
