Subject: [ 025/105] module: taint kernel when lve module is loaded
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Garrett <mjg59@...f.ucam.org>
commit c99af3752bb52ba3aece5315279a57a477edfaf1 upstream.
Cloudlinux have a product called lve that includes a kernel module. This
was previously GPLed but is now under a proprietary license, but the
module continues to declare MODULE_LICENSE("GPL") and makes use of some
EXPORT_SYMBOL_GPL symbols. Forcibly taint it in order to avoid this.
