[PATCH] qemu-xen: Intel GPU passthrough, fix OpRegion mapping.
The OpRegion shouldn''t be mapped 1:1 because the address in the host
can''t be used in the guest directly.
This patch traps read and write access to the opregion of the Intel
GPU config space (offset 0xfc).
To work correctly this patch needs a change in hvmloader.
HVMloader will allocate 2 pages for the OpRegion and write this address
on the config space of the Intel GPU. Qemu

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.
