PCI device assignment to guests (userspace)
Userspace patches for the pci-passthrough functionality. The major updates since the last post are: - Loop to add passthrough devices in pc_init1 - Handle errors in read/write calls - Allow invocation without irq number for in-kernel irqchip Other than this, several small things were fixed according to review comments received last time.

[PATCH]vtd: Fix for irq bind failure after PCI attaching 32 times
vtd: Fix for irq bind failure after PCI attaching 32 times Originally when detaching a PCI device, pirq_to_emuirq and pirq_to_irq are freed via hypercall do_physdev_op. Now in function pt_irq_destroy_bind_vtd, duplicated logic is added to free pirq_to_emuirq, but not pirq_to_irq. This causes do_physdev_op fail to free both emuirq and irq. After attaching a PCI device for 32 times, irq resources
