:(. I don't know if we will ever solve this license mess... Looking at 
the list of platform using cpu_up_send_sgi(), all the platforms are 10+ 
years old and to be honest except maybe the rcar2 development platforms. 
I doubt there are anyone using them.
So I would be tempted to get rid of them and mandate PSCI when booting 
on Xen.
Bertrand, Michal, Stefano any thoughts?

Meanwhile for this patch:
