Subject: [PATCH 01/13] tracing: Extract duplicate ftrace_raw_init_event_foo()

Define ftrace_raw_init_event_foo() for each event class rather
than for each event:

   text    data     bss     dec     hex filename
5459553 2005772 7103796 14569121         de4ea1 vmlinux.o.old
5456157 2005772 7103796 14565725         de415d vmlinux.o
