Some issues with this. First linux-headers is for linux as a host.
This is for linux as a guest, so belongs in include/standard-headers.
Second, please add to scripts/update-linux-headers.sh in a 1st patch,
then add the file in the second patch.
Thanks; now I understand the differences. I'll do that in next version.
