Right on! This is excellent news. I've tested this set on top of -rc4
plus the patch mentioned below, and I'm not seeing regressions on
the platforms I tested with. Wake up to smsc911x ping with off-idle
still works on omap3.

I only briefly tested on omap1 (osk5912), so I'like to wait for
Aaro's ack before this gets merged.

I found one build error, other than that, for the whole series
please feel free to add:
