All applied, thanks.

A few patches here touch (v)gic-v2.c, which I assume means some sort of
update to the gic v3 series is going to be needed? Can you offer any
advice to Vijay (ccd)?

From "git log --oneline origin/staging..HEAD -- xen/arch/arm/*gic-v2.c"
these seem to be:

50d8fe8 xen/arm: make accesses to desc->status flags atomic
446df2f xen/arm: take the rank lock before accessing ipriority

        These two should be trivial to carry over.

5bd62a7 xen/arm: physical irq follow virtual irq

        gic v3 version will be different, but should be pretty easy?

6e42345 xen/arm: inflight irqs during migration

        This one looks a bit scary, and would need similar handling for
        the IROUTER stuff, I think?

5b3a817 xen/arm: observe itargets setting in vgic_enable_irqs and vgic

        A new vgic_ops hook needs implementing.

Ian.
