Subject: [PATCH -tip  0/3] kprobes, x86: Move optprobe on top of int3-based instruction patching
Date: Thu, 18 Jul 2013 20:47:38 +0900	[thread overview]
Message-ID: <20130718114738.26675.85914.stgit@mhiramat-M0-7522> (raw)

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,
