Thanks Stefan.

The file does not seem to come from the linux kernel and google
found a bunch of other files with the same name, but they either
seemed to be un-related files (eg one from OpenBSD) or to be
dervied from this file in Qemu.

That means the file is under the default license for Qemu. The
LICENSE file simply says "GNU General Public License" without
specifying which version of that license. Does this mean GPLv2,
GPLv2+, GPL3 or GPLv3+?

Sorry about these annoying questions, but lawyers tend to be
sticklers for these minor details.

Cheer,
Erik
