Merge tag 'perf-tools-fixes-for-v6.4-2-2023-05-30' into perf-tools-next
perf tools fixes for v6.4: 2nd batch
- Fix BPF CO-RE naming convention for checking the availability of fields on
'union perf_mem_data_src' on the running kernel.
- Remove the use of llvm-strip on BPF skel object files, not needed, fixes a
build breakage when the llvm package, that contains it in most distros, isn't
installed.
- Fix tools that use both evsel->{bpf_counter_list,bpf_filters}, removing them from a
union.
- Remove extra "--" from the 'perf ftrace latency' --use-nsec option,
previously it was working only when using the '-n' alternative.
- Don't stop building when both binutils-devel and a C++ compiler isn't
available to compile the alternative C++ demangle support code, disable that
feature instead.
- Sync the linux/in.h and coresight-pmu.h header copies with the kernel sources.
- Fix relative include path to cs-etm.h.
