[PATCH v2 0/5] kretprobe fixes

[Naveen N. Rao]

I'm including all patches (generic and powerpc changes) in
this series as suggested by Masami.

v1 patches:
https://marc.info/?l=linux-kernel&m=148718276424380
https://marc.info/?l=linux-kernel&m=148723314105453&w=2

Patches 1 and 2 are the same as v1.
Patch 3 is updated to include a line in ftrace README.
Patch 4 is new.
Patch 5 is updated to consider ftrace README.


Thanks,
Naveen
