[PATCH v3 0/7] Fixes for perf probe issues on ppc

From: Naveen N. Rao
Date: Tue Apr 28 2015 - 08:07:15 EST

This patchset fixes various issues with perf probe on powerpc across ABIv1 and
- in the presence of DWARF debug-info,
- in the absence of DWARF, but with the symbol table, and
- in the absence of debug-info, but with kallsyms.

I have moved all patches to use __weak functions. Kindly take a look and let me
know if this is what you had in mind.

- Naveen

Changes since v2:
The primary change is with the use of __weak functions instead of compiler
macros. Along with that, I have also addressed all previous review comments
(*). Individual patches have the detailed changelog. Please note that I have
dropped the first (kernel) patch from the last series since it has been pushed
upstream. This series now only includes the rest of the patches.
