I think it's -pirq at index irq, i.e. I don't think IRQ gets
negated as far as the radix tree goes. info->arch.irq gets a
negative value stored, yes.
When force unbinding a MSI the used IRQ would get added to the domain
irq-pirq tree as -irq -pirq, thus preventing the same IRQ to be used
by the domain. Doing so for MSI allocated IRQs prevents the same IRQ
to be used for any other device, since MSI IRQs are allocated and
deallocated on demand unl
