matshch opened a new pull request, #47563:
URL: https://github.com/apache/arrow/pull/47563
### Rationale for this change
On newer Apple silicon CPUs there is more L2 CPU cache than expected by the
current unit tests. This results in the unit test failing:
```
/tmp/nix-build-arrow-cpp-20.0.0.drv-0/source/cpp/src/arrow/util/io_util_test.cc:1099:
Failure
Value of: l2 >= 32 * 1024 && l2 <= 12 * 1024 * 1024
Actual: false
Expected: true
unexpected L2 size: 16777216
[ FAILED ] CpuInfo.Basic (0 ms)
```
### What changes are included in this PR?
The expected L2 CPU cache range is increased to 32KiB-64MiB to accommodate
newer CPUs.
### Are these changes tested?
Yes.
### Are there any user-facing changes?
No.
