Subject: [PATCH -tip  0/5] Kprobes updates

Hi,

This series of patches fixes some code/docs which are related to
kprobes (especially optprobe).
First 2 resend patches update document and selftest since
optprobe changes kprobes behavior.
Next 2 patches fix double get_cpu() by using __stop_machine().
And the last patch makes text_poke_smp() depending on
stop_machine() on smp, because without stop_machine(),
it can't ensure safety on smp.

Thank you,
