I added the patch because it is very small and only affects psci_smp.c,
so it is not a problem for me to carry it in the xen-arm tree.
But I see your point, I'll remove it.
As a side note for the arm-soc maintainers in CC, even though I
proactively added the PSCI and the smp_init patches
(http://marc.info/?l=linux-kernel&m=136716063717467&w=2) to linux-next
to make sure they get enough exposure for this merge window, I would
appreciate if you could pick them up in your tree. I think they should
to Linus via arm-soc.
