These patches complement Part I of the feature at: https://lore.kernel.org/linux-hyperv/20260512020259.1678627-1-mrathor@linux.microsoft.com/T/#t Testing and other details are listed there. Changes in V1: o rebase to above V3 of Part I o check for NULL irqdata->parent_data->chip before calling irq_chip_unmask_parent().
