In selftests/amd-pstate, tbench and gitsource microbenchmarks are

The plurality of this sentence needs some work. I suggest:
s,relative,the relative,
s,are broken,is broken,
Fixed this by using absolute paths.
The tense is wrong.

If you're using os.path.join, shouldn't you not be hardcoding a "/" in
there?
IE it should be:
sys.path.append(os.path.join(os.path.dirname(__file__), "..",
"intel_pstate_tracer"))
#import intel_pstate_tracer
I think another patch should remove this commented line, it conveys zero
information.

If you change to /bin/bash instead of /bin/sh you could use pushd/popd
instead. If your goal is to keep compatibility with things like
/bin/dash then this makes ense.
