Applied 4-5 to wq/for-7.4.

One note: if pwq allocation fails partway through
apply_wqattrs_prepare(), the already allocated pwqs are released through
pwq_release_worker, which isn't created until workqueue_init(). Percpu
workqueues are created before that, so an allocation failure in that
window now oopses instead of failing cleanly. An allocation failing that
early is unrecoverable anyway, so this doesn't need handling, but it
probably deserves a comment.

Thanks.
