Hi all,

After merging the perf tree, today's linux-next build (native perf)
failed like this:

cc1: all warnings being treated as errors

Caused by commit

f90a29144887 ("perf test: Remove C test wrapper for attr.py")

This is a native build of perf on ppc64le using

make -C tools/perf -f Makefile.perf NO_BPF_SKEL=1

I have merged the perf tree from next-20241010 for today.
