No functional change. The request to allocate the irq above NR_IRQS_LEGACY is completely pointless as the implementation enforces that the dynamic allocations are above the GSI interrupts, which includes the legacy PIT irqs. This does not replace the requirement to move x86 to irq domains, but it limits the mess to some degree.
