Subject: [PATCH v2 0/4] perf test: "object code reading" test fixes

A few fixes around the object code reading test. The first patch
appears to be unrelated, but in this case the data symbol test is
broken on Arm N1 by the second commit.

Changes since V1:
  * Put data symbol test fix first so that bisecting still works on N1
  * Instead of skipping "test data symbol" on N1, add some noise into
    the loop.
  * Add a commit to replace the only usage of lscpu in the tests with
    uname

James Clark (4):
  perf tests: Make "test data symbol" more robust on Neoverse N1
  perf tests: Apply attributes to all events in object code reading test
  perf map: Remove kernel map before updating start and end addresses
  perf tests: Remove dependency on lscpu
