2025-07-03perf header: Fix pipe mode header dumpingIan Rogers
The pipe mode header dumping was accidentally removed when tracing of header feature events in pipe mode was added. Minor spelling tweak to header test failure message.

2025-06-30perf test: perf header test fails on s390Thomas Richter
commit 2d584688643fa ("perf test: Add header shell test") introduced a new test case for perf header. It fails on s390 because call graph option -g is not supported on s390. Also the option --call-graph dwarf is only supported for the event cpu-clock. Remove this option and the test succeeds.
