Subject: [PATCH] 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.
