    tracing: Extract duplicate ftrace_raw_init_event_foo() · 87d9b4e1

    Use a generic trace_event_raw_init() function for all event's raw_init
    callbacks (but kprobes) instead of defining the same version for each
    of these.
    This shrinks the kernel code:
    
       text    data     bss     dec     hex filename
    5355293 1961928 7103260 14420481         dc0a01 vmlinux.o.old
    5346802 1961864 7103260 14411926         dbe896 vmlinux.o
    
    raw_init can't be removed, because ftrace events and kprobe events
    use different raw_init callbacks. Though it's possible to totally
    remove raw_init, I choose to leave it as it is for now.
