Title:
  No driver provided for X-Gene's hardware RNG

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Committed
Status in “linux” source package in Utopic:
  Fix Released

Bug description:
  [Impact]
  User has a system with a built-in random number generator that the OS cannot use.

  [Test Case]
  Make sure rng-tools is uninstalled.
  Reboot with this driver, verify that it is automatically loaded. Leave system idle for this test.
  In one terminal, run 'watch cat /proc/sys/kernel/random/entropy_avail', and note that the minor fluctuation in available entropy over time. Install rng-tools, and notice that entropy shoots up and grows at a faster rate than previously.

  [Regression Potential]
  If this driver is buggy it could cause e.g. an oops or a panic that would not otherwise have occurred.
