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
