[PATCH 1/1] ftrace: adding other non-leaving .text sections

[Liming Wang <liming.wang@windriver.com>]

Please review this patch, and I don't know whether new sections will conflict 
with sched tracer or others. 
This patch is against Steven tree's tip/devel latest commit.

Impact: improve 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.
