After some debugging with Paul, I found that the patch being reverted here was the cause of another regression: GPIO context not being properly restored after off mode. This caused the nfsroot problems in off-mode on boards with ethernet devices with GPIO IRQ lines (Overo, 37xx EVM, ...) Updating changelog, and will post v2 shortly.
