show_sampling_rate_(min|max): THIS INTERFACE IS DEPRECATED, DON'T USE IT.
You can use wider ranges now and the general
cpuinfo_transition_latency variable (cmp. with user-guide.txt) can be
used to obtain exactly the same info:
show_sampling_rate_min = transtition_latency * 500 / 1000
show_sampling_rate_max = transtition_latency * 500000 / 1000
(divided by 1000 is to illustrate that sampling rate is in us and
transition latency is exported ns).
