ftrace: adding other non-leaving .text sections
Impact: widen the scope of recordmcount.pl Besides .text section, there are three .text sections that won't be freed after kernel booting. They are: .sched.text, .spinlock.text and .kprobes.text, which contain functions we can trace. But the last section ".kprobes.text" is particular, which has been marked as "notrace", we ignore it. Thus we add other two sections. Signed-off-by: Liming Wang <liming.wang@windriver.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
