perf/urgent fixes:
- Fix the build on Clear Linux, coping with redundant declarations of function prototypes in python3 header files by adding -Wno-redundant-decls to build with PYTHON=python3 (Arnaldo Carvalho de Melo) - Fixes for processing inline frames in backtraces using DWARF based unwinding (Milian Wolff) - Cope with bad DWARF info for function names for inline frames,not trying to demangle this symbol. Problem reported with rust but reproduced as well with C++. Problem reported to the libbpf maintainers (Milian Wolff) - Fix python export to postgresql and sqlite code (Adrian Hunter) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQR2GiIUctdOfX2qHhGyPKLppCJ+JwUCW7eGGwAKCRCyPKLppCJ+ JzAWAP4rGO2bZmvRFBmg9go5xeYZmOOy8pk9zHslslrNlSSyrwEAvyI1Fk/YYR4I 9UDE+/F9pey7BVuY5V8pFplEEcFF8gY= =K7kp -----END PGP SIGNATURE----- Merge tag 'perf-urgent-for-mingo-4.19-20181005' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: - Fix the build on Clear Linux, coping with redundant declarations of function prototypes in python3 header files by adding -Wno-redundant-decls to build with PYTHON=python3 (Arnaldo Carvalho de Melo) - Fixes for processing inline frames in backtraces using DWARF based unwinding (Milian Wolff) - Cope with bad DWARF info for function names for inline frames,not trying to demangle this symbol.
