Following is my alternative to irq routing. The differences compared to Sheng's version are:
- A single ioctl to replace the entire routing table, instead of add/remove ioctls for individual routing entries. Routing changes are rare, and we need to track the entire table in userspace anyway (for save/restore, and for user irqchip). As a side effect changes are atomic. - Interrupt numbers are allocated by userspace, instead of the kernel - I implemented irqchip routings rather then MSIs, it should be easy to add MSIs later on. Please review and comment.
