I'm trying to run rr (version 4.5.0) on an i7-7700 cpu and I get this error:

[FATAL /home/roc/rr/rr/src/PerfCounters.cc:162:get_cpu_microarch() errno:
EOPNOTSUPP] CPU 0x906e0 unknown.

However, i7-7700 is a Kaby Lake cpu and the release notes for version 4.5
say that support for Kaby lake was added. Is this just a bug in how rr is
trying to identify the cpu or am I missing something? -wade
