Bug description:
  As of Linux 3.5, it is not possible to update the SecureBoot database
  from userspace because the sysfs implementation only supports variable
  data up to 1KB in size and this is exceeded by even a minimum key
  database of one key.

  Matt Fleming has accepted a patch from Matthew Garrett to add a new
  filesystem that supports larger variables.  Please consider
  backporting this (as an SRU) to both quantal and precise.
