[Message part 3 (text/plain, inline)]
The test tests/cp/proc-short-read.sh attempts to remove common
differences in the output of /proc/cpuinfo:

    # adjust varying parts
    sed '/MHz/d; /bogomips/d;' 1 > proc.cp || framework_failure_
    sed '/MHz/d; /bogomips/d;' 2 > proc.cat || framework_failure_

However the string "bogomips" may differ in capitalization across
different architectures [1].

Testing on a big.LITTLE system uncovered this assumption.

    Linux DietPi 5.4.225-odroidxu4 #22.11.1 SMP PREEMPT Wed Nov
    30 10:55:16 UTC 2022 armv7l GNU/Linux

Still present as of 9581c4b59d2e11cd090613cd300a833b4441d2b5.

Proposed patch attached, which aims to be minimally invasive.
