Hi Mark,

Thank you for the report.

At first glance, this appears to be caused by a corrupted/truncated
kernel/kheaders.o on the build runner rather than an issue in the patch
itself, no? Could you try a clean rebuild of arm64 allyesconfig with the
commits re-applied? It should build cleanly.

I will take a detailed look.


Kind regards,
