Subject: [PATCH] kernel: trace: remove __init from race_selftest_startup_function()
 and trace_selftest_startup_function_graph()

Like other trace_selftest_startup_*, trace_selftest_startup_function()
and trace_selftest_startup_function_graph() need in normal section, or
may cause section mismatch.

The related warnings:

    LD      kernel/trace/built-in.o
  WARNING: kernel/trace/built-in.o(.data+0x154c): Section mismatch in reference from the variable function_trace to the function .init.text:trace_selftest_startup_function()
  The variable function_trace references
  the function __init trace_selftest_startup_function()
  If the reference is valid then annotate the
  variable with __init* or __refdata (see linux/init.h) or name the variable:
  *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
