These function are all called from assembler files, or from inline assembler, so there is no immediate need for a prototype in a header, but if -Wmissing-prototypes is enabled, the compiler warns about them: arch/x86/xen/efi.c:130:13: error: no previous prototype for 'xen_efi_init' [-Werror=missing-prototypes] arch/x86/platform/pvh/enlighten.c:120:13: error: no previous prototype for 'xen_prepare_pvh' [-Werror=missing-prototypes] arch/x86/xen/enlighten_pv.c:1233:34: error: no previous prototype for 'xen_start_kernel' [-Werror=missing-prototypes] arch/x86/xen/irq.c:22:14: error: no previous prototype for 'xen_force_evtchn_callback' [-Werror=missing-prototypes] arch/x86/entry/common.c:302:24: error: no previous prototype for 'xen_pv_evtchn_do_upcall' [-Werror=missing-prototypes] Declare all of them in an appropriate header file to avoid the warnings. For consistency, also move the asm_cpu_bringup_and_idle() declaration out of smp_pv.c.
