xen/trace: Fix compile error when CONFIG_XEN_PRIVILEGED_GUEST is not set with CONFIG_XEN and CONFIG_FTRACE set we get this: arch/x86/xen/trace.c:22: error: ‘__HYPERVISOR_console_io’ undeclared here (not in a function) arch/x86/xen/trace.c:22: error: array index in initializer not of integer type arch/x86/xen/trace.c:22: error: (near initialization for ‘xen_hypercall_names’) arch/x86/xen/trace.c:23: error: ‘__HYPERVISOR_physdev_op_compat’ undeclared here (not in a function) Issue was that the definitions of __HYPERVISOR were not pulled if CONFIG_XEN_PRIVILEGED_GUEST was not set.
