CVE: N/A

----------------------------------------

The commit 0c740d0a ("introduce for_each_thread() to replace the buggy
while_each_thread()") replace while_each_thread. while_each_thread()
and next_thread() should die, almost every lockless.

So use for_each_process_thread which is more safer than others to
check the livepatch activeness function when enable.
