This patch set is applied to supprot the mbigen device. Mbigen means message based interrupt generator. It locate in ITS or out side of ITS.
In fact, mbigen is a kind of interrupt controller collects the irq form Non-PCI devices and generate msi interrupt. Hisilicon designed mbigen to reduce the wired interrupt number connected to GIC. In these patches, the interrupts from Non-PCI devices are named as MBI to distiguish between legacy MSI interrupt from PCI devices. As a MSI interrupt controller, the mbigen is used as a child domain of MSI domain just like PCI devices. So,in order to support the mbigen interrupt controller, the msi.c and its-gic-v3-its.c are changed.
