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
