Subject: linux-next: build failure after merge of the perf tree

Hi all,

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

cc1: all warnings being treated as errors

Presumably caused by commit

  7eca67cf3dab ("perf tools powerpc: Use generic syscall table scripts")

This is a native powerpc build of perf on a little endian host.

I have used the perf tree from next-20250109 for today.
