[PATCH 0/5] Fixes on perf unwind

[He Kuang]

hi,

Patch 1-3 fix wrongly used PERF_REG_SP/IP by redefining
those macros in the wrapper file according to the target platform, for
example in "util/libunwind/x86_32.c".
The first 3 patches have been acked-by "Jiri Olsa" and not touched.

Patch 4 catches an error on python build_ext build.

Patch 5 fixes a NULL pointer deference which can cause segfault when
the desired dso is not found.

Thank you.

He Kuang (5):
  perf unwind: Change macro names of perf register
  perf unwind: Fix wrongly used regs for x86_32 unwind
  perf unwind: Fix wrongly used regs for aarch64 unwind
  perf tools: Let python use correct gcc for build_ext
  perf tools: Fix NULL pointer deference when vdso not found
