Subject: [PATCH v3 0/7] Fixes for perf probe issues on ppc
Date: Tue, 28 Apr 2015 17:35:33 +0530 [thread overview]
Message-ID: <cover.1430217967.git.naveen.n.rao@linux.vnet.ibm.com> (raw)
This patchset fixes various issues with perf probe on powerpc across ABIv1 and
ABIv2:
- 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.
Arnaldo,
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.
Thanks!
- 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.
