This now seems to complain about a commit which simply adds a file to
update-linux-headers.sh and simultaneously adds the newly-imported
file. Such as commit aa274c33c39e7de981dc195abe60e1a246c9d248.

Was that the intent? Do we really need to have *three* separate
commits, one for update-linux-headers.sh, one to import the new header,
and then the third to add the QEMU code which actually uses the new
header?
