Hi Eric,

This series proposes some fixes that appeared to be necessary
to integrate IRQ forwarding in KVM/VFIO.

- deactivation of the forwarded IRQ in irq_disabled case
- a specific handling of forwarded IRQ into the VGIC state machine.
- deactivation of physical IRQ and unforwarding on vgic destruction
- rb_tree lock in vgic.c

Integrated pieces can be found at
ssh://git.linaro.org/people/eric.auger/linux.git
on branch irqfd_integ_v9

What are the dependencies for this at this point?

I assume it relies at least on the split EOI/priority drop changes?

Yes it now only depends on split EOI/priority drop changes since
"genirq: Saving/restoring the irqchip state of an irq line" now is
upstreamed.

Are you going to respin this when there are newer versions of the
dependencies out, or what are the plans?

Yes I will respin according to new versions. I am currently using a
rebased version of Marc's original RFC "ARM: Forwarding physical
interrupts to a guest VM" (http://lwn.net/Articles/603514/) which is a
superset of [PATCH] genirq: Add support for priority-drop/deactivate
interrupt controllers.

ok, once there's movement on the dependency and you respin, I'll review
the rest of this in detail.
