[PATCH] backports: backport power efficient workqueues

[PATCH] backports: backport power efficient workqueues

[Johannes Berg]

From: Johannes Berg <johannes.berg@intel.com>

These only exist starting from 3.11, and wireless code will
start using them soon. Backport them as simple defines using
the corresponding non-power-efficient workqueues.
