The OMAP patch was accepted for 3.10, and I'm sure we will have good
patches for the other bus glues as well, but the bug is also present on
3.9, and the proper patches are too invasive now to get merged there.

patches out in time :(

It won't be merged in 3.10, but in that case Debian can backport the proper
patches from 3.10.
