    [PATCH] sched: tasks cannot run on cpus onlined after boot
    Commit 5c1e176781f43bc902a51e5832f789756bff911b ("sched: force /sbin/init
    off isolated cpus") sets init's cpus_allowed to a subset of cpu_online_map
    at boot time, which means that tasks won't be scheduled on cpus that are
    added to the system later.
    Make init's cpus_allowed a subset of cpu_possible_map instead.  This should
    still preserve the behavior that Nick's change intended.
    Thanks to Giuliano Pochini for reporting this and testing the fix:
