Re: [PATCH 0/4 v6] arm: introduce psci_smp_ops and use them on Xen

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

Arnd, Olof,
do you have any thoughts on this series?
Would you be happy to carry it in the arm-soc tree?

The last patch, "xen/arm: introduce xen_early_init, use PSCI on xen" has
a (small) dependency on this series:

http://marc.info/?l=linux-kernel&m=136430893610688&w=2

would you be OK with taking that one too, or should that go through the
Xen tree?

Cheers,

Stefano
