Subject: [PATCH v3 0/7] powerpc: a few kprobe fixes and refactoring

v2:
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1375870.html

v3 changes:
- Patch 3/5 in the previous series ("powerpc: introduce a new helper to
  obtain function entry points") has been dropped from this series and
  will instead be posted as part of the KPROBES_ON_FTRACE patchset.
- Patch 5/5 in the previous series ("powerpc: kprobes: emulate
  instructions on kprobe handler re-entry") has been split into two
  patches as recommended by Masami. They represent patches 6/7 and 7/7
  in this series.
- Patches 3/7 and 4/7 are new in this series to address review comments
  from David Laight.
