So, this is another issue, why is it not > recognized as a xen domain ? xen_domain() is correctly set quite late on ARM. I have already pointed out this issue when the patch to modify xen_raw_console_write was sent on the mailing (see https://lkml.org/lkml/2013/10/24/343). But, it seems that my comment was not considered when the patch was pushed. Ian Campbell has offered a solution here: https://lkml.org/lkml/2013/10/26/21, but I never had the time to send it.
