MIPS: Use NOKPROBE_SYMBOL() instead of __kprobes annotation
If define CONFIG_KPROBES, __kprobes annotation forces the whole function
into the ".kprobes.text" section, NOKPROBE_SYMBOL() only stores the given
function address in the "_kprobe_blacklist" section which is introduced
to maintain kprobes blacklist.
Modify the related code to use NOKPROBE_SYMBOL() to protect functions from
kprobes instead of __kprobes annotation under arch/mips.
No obvious functional change in this patch, some more work needs to be done
to fix the kernel panic when execute the following testcase on mips:
# cd tools/testing/selftests/ftrace
# ./ftracetest test.d/kprobe/multiple_kprobes.tc
