Hi Magnus,

Thanks for the patch.

I've noticed today that KZM9G doesn't boot v3.10-rc2 with 
CONFIG_AUTO_ZRELADDR=y. While not caused by this patch, that's something that 
will need to be fixed to support multi-arch kernels. I'm not too familiar with 
early boot code, would you be able to have a look at this ?
