David Vrabel	1fe565517b	xen/events: use the FIFO-based ABI if available ... Implement all the event channel port ops for the FIFO-based ABI. If the hypervisor supports the FIFO-based ABI, enable it by initializing the control block for the boot VCPU and subsequent VCPUs as they are brought up and on resume. The event array is expanded as required when event ports are setup. The 'xen.fifo_events=0' command line option may be used to disable use of the FIFO-based ABI.
