The main change from the patches I sent out earlier this week is support for guests that use the PIC. A callback for PIC irq ack handling is also introduced. Currently, there's no mechanism to register/unregister callers to the irq ack callbacks, but they can be added when there's more than one user for the functionality. Please review.

Hi all, The series is a draft of generic MSI driver that supports PCI and Non-PCI device which have MSI capability. If you're not interested it, sorry for the noise. The series is based on Linux-3.16-rc1. MSI was introduced in PCI Spec 2.2. Currently, kernel MSI driver codes are bonding with PCI device. Because MSI has a lot advantages in design. More and more non-PCI devices want to use
