Much of this overhead is new with the recent interconnect changes, but even without those changes we still had some overhead that we could avoid. Let's avoid all of it. These changes are atop the Qualcomm tree to avoid merge conflicts. If they look good, the most expedient way to land them is probably to get Ack's from Mark and land then via the Qualcomm tree. Most testing was done on the Chrome OS 5.4 tree, but sanity check was done on mainline.
