Subject: [PATCH -tip  0/3] kprobes,
 x86: Move optprobe on top of int3-based instruction patching

Hi,

Here is a series of kprobes and x86 patches for moving
optprobe (jump optimized kprobe) onto the int3-based
instruction patching (a.k.a. text_poke_bp, introduced by
Jiri Kosina).

Since this completely moves text_poke_smp* user to new
text_poke_bp, I also remove the old text_poke_smp* code
from alternative.c. As a side effect, it also fixes a
Kconfig warning about CONFIG_STOP_MACHINE dependency
confliction.

Thank you,

---
