3.16.44-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "K. Y. Srinivasan" <kys@microsoft.com>
commit 8de0d7e951826d7592e0ba1da655b175c4aa0923 upstream.
The current delay between retries is unnecessarily high and is negatively affecting the time it takes to boot the system.
