Arnaldo Carvalho de Melo 0b157b1000 perf annotate: Add 'ret' (intel disasm style) as an alias for 'retq' 
When we use the 'intel' disassembler style we get 'ret' instead of
'retq', so add that as an alias.

  # perf annotate --disassembler-style=intel --stdio2 acpi_processor_ffh_cstate_enter > before

Apply this patch and then:

  # perf annotate --disassembler-style=intel --stdio2 acpi_processor_ffh_cstate_enter > after
  # diff -u before after
