Avi Kivity f6790af6bc memory: use AddressSpace for MemoryListener filtering
Using the AddressSpace type reduces confusion, as you can't accidentally
supply the MemoryRegion you're interested in.

Avi Kivity 12b40e471f xen_pt: use separate MemoryListeners for memory and I/O
Using an unfiltered memory listener will cause regions to be reported
fails multiple times if we have more than two address spaces.  Use a separate
listener for memory and I/O, and utilize MemoryListener's address space
filtering to fix this.

Xudong Hao aabc8530c7 qemu/xen: Add 64 bits big bar support on qemu
Currently it is assumed PCI device BAR access < 4G memory. If there is such a
device whose BAR size is larger than 4G, it must access > 4G memory address.
This patch enable the 64bits big BAR support on qemu.

Stefano Stabellini fb5b0c6d5c fix Xen compilation
xen_pt_unregister_device is used as PCIUnregisterFunc, so it should
match the type.

Paolo Bonzini 753d5e14c4 memory: pass EventNotifier, not eventfd
Under Win32, EventNotifiers will not have event_notifier_get_fd, so we
cannot call it in common code such as hw/virtio-pci.c.  Pass a pointer to
the notifier, and only retrieve the file descriptor in kvm-specific code.
