I don't think much action is needed: whenever someone integrates the
workqueue tree with these reboot changes, or the workqueue changes hit
upstream, a s/PF_THREAD_BOUND/PF_NO_SETAFFINITY should do the trick,
right?

Btw., if that's true then the workqueue tree should probably grow this
helper:

#define PF_THREAD_BOUND PF_NO_SETAFFINITY

migration/backport helper, which can be removed in v3.11 or so.

Thanks,

Ingo
