Subject: [PATCH 0/4] perf: Support AMD range breakpoints

Hi,

I've made it wait too much so I'm posting that for review now. This
implements range breakpoints on some AMD machine by extending the length
field.

Any comment?

Thanks.

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
