Hi Tejun,

After merging the workqueues tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

kernel/workqueue.c: In function 'workqueue_init_early':
kernel/workqueue.c:5561:56: error: 'cpu_isolated_map' undeclared (first use in this function)
  cpumask_andnot(wq_unbound_cpumask, cpu_possible_mask, cpu_isolated_map);
                                                        ^

Caused by commit

  b5149873a0c2 ("workqueue: respect isolated cpus when queueing an unbound work")

interacting with commit

  edb9382175c3 ("sched/isolation: Move isolcpus= handling to the housekeeping code")

from the tip tree.

I am not sure how to fix this, so I have reverted b5149873a0c2 for today.

I'm reverting it from my tree.  Tal, can you please spin up a new
patch against the sched branch?  Let's either route it through sched
branch or try again after the rc1.

Thanks.
