Re: [PATCH v2] perf test: Record kcore for the CoreSight callchain test

The CoreSight callchain test traces both userspace and kernel execution and checks the callchain across a syscall.

Add --kcore to perf record to save the running kernel image alongside the trace data so perf script can use it to decode the kernel trace. If kcore is not available, the test will be skipped.

Thanks, applied to perf-tools-next, for v7.4.
