Summary:

* Extend breakpoint tools and core to support address range through perf
  event with initial backend support for AMD extended breakpoints.
  Syntax is:

        perf record -e mem:addr/len:type

  For example set write breakpoint from 0x1000 to 0x1200 (0x1000 + 512)

        perf record -e mem:0x1000/512:w

* Clean up a bit breakpoint code validation

Thanks,
	Frederic

Jacob Shin (4):
      perf/x86/amd: AMD support for bp_len > HW_BREAKPOINT_LEN_8
      perf tools: allow user to specify hardware breakpoint bp_len
      perf tools: add hardware breakpoint bp_len test cases
      perf/x86: Remove get_hbp_len and replace with bp_len
