genirq/msi: Export functions to allow MSI domains in modules
The Linux kernel already has the concept of IRQ domain, wherein a
component can expose a set of IRQs which are managed by a particular
interrupt controller chip or other subsystem. The PCI driver exposes
the notion of an IRQ domain for Message-Signaled Interrupts (MSI) from
PCI Express devices. This patch exposes the functions which are
necessary for creating a MSI IRQ domain within a module.
[ tglx: Split it into x86 and core irq parts ]
