Your patch is along the write lines but should actually check for IRQ_GUEST
flag. I've applied a bigger patch as 18547. It also I think simplifies the
logic of 18539 in a number of respects, especially by splitting
pirq_guest_unbind() into two interface functions. Let me know how you get on
with it!
