Sorry for the super late reply and happy new year!

As Vegard noted we can change the header to <linux/kernel.h>
to avoid the build issue.  I don't expect more changes in this
code so it's unlikely we have conflicts here.  Let me know if
it happens later.

Anyway this code is needed to handle JIT-dump binaries
generated by perf inject.  I'll send a patch if it's ok to you.

Thanks,
Namhyung
