Upgrade torvalds/linux to version 3.14.4 or higher.

Overview

Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions. The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device.
