Subject: [PATCH v3 0/5] powerpc: add support for KPROBES_ON_FTRACE
Date: Wed, 12 Apr 2017 16:39:21 +0530 [thread overview]
Message-ID: <cover.1491994965.git.naveen.n.rao@linux.vnet.ibm.com> (raw)
v2:
https://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg114659.html
For v3, this has only been rebased on top of powerpc/next and carries a
minor change to patch 4/5. No other changes.
Also, though patch 3/5 is generic, it needs to be carried in this
series as we crash on powerpc without that patch.
- Naveen
Masami Hiramatsu (1):
kprobes: Skip preparing optprobe if the probe is ftrace-based
Naveen N. Rao (4):
powerpc: ftrace: minor cleanup
powerpc: ftrace: restore LR from pt_regs
powerpc: kprobes: add support for KPROBES_ON_FTRACE
powerpc: kprobes: prefer ftrace when probing function entry
