    Subject[PATCH 3/4] drivers: xen: Move prototype declaration to appropriate header file from arch/x86/xen/xen-ops.h
    Move prototype declaration to header file include/xen/xen-ops.h from
    arch/x86/xen/xen-ops.h because they are used by more than one file.

    This eliminates the following warning in drivers/xen/events/:
    drivers/xen/events_2l.c:1231:13: warning: no previous prototype for ‘xen_debug_interrupt’ [-Wmissing-prototypes]
