Changes in V7:
  - In arm-cs-trace-disasm.py, fix print message core dump resulting
    from mixed type arithmetic.
  - Modify CS_ETM_TRACE_ON filter to filter zero start_addr. The
    CS_ETM_TRACE_ON message is changed to print only in verbose mode.
  - Removed verbose mode only notification for start_addr/stop_addr
    outside of dso address range.

Changes in V6:
  - In arm-cs-trace-disasm.py, zero map_pgoff for kernel files. Add
    map_pgoff to start/end address for dso not found message.
  - Added "Reviewed-by" trailer for patches 1-3 previously reviewed
    by Leo Yan in V4 and V5.

Changes in V5:
  - In symbol-elf.c, branch to exit_close label if open file.
  - In trace_event_python.c, correct indentation. set_sym_in_dict
    call parameter "map_pgoff" renamed as "addr_map_pgoff" to
    match local naming.

Changes in V4:
  - In trace-event-python.c, fixed perf-tools-next merge problem.

Changes in V3:
  - Rebased to linux-perf-tools branch.
  - Squash symbol-elf.c and symbol.h into same commit.
  - In map.c, merge dso__is_pie() call into existing if statement.
  - In arm-cs-trace-disasm.py, remove debug artifacts.

Changes in V2:
  - In dso__is_pie() (symbol-elf.c), Decrease indentation, add null pointer
    checks per Leo Yan review.
  - Updated mailing list distribution.

Steve Clevenger (4):
  Add dso__is_pie call to identify ELF PIE
  Force MAPPING_TYPE__IDENTIY for PIE
  Add map pgoff to python dictionary based on MAPPING_TYPE
  Adjust objdump start/end range per map pgoff parameter
