Title:
  PAE check prevents Precise to Trusty upgrades on non-Intel ports

Status in “ubuntu-release-upgrader” package in Ubuntu:
  In Progress

Bug description:
  do-release-upgrade refuses to upgrade a powerpc 12.04 installation to
  Trusty due to "pae " not being found in /proc/cpuinfo.

  I was able to track the problem down to the _checkPae() function in
  DistUpgrade/DistUpgradeQuirks.py. It unconditionally enforces the PAE
  flag to be found in cpuinfo without doing any checks on the CPU
  architecture.
