This also affects 14.04 LTS, although to a slightly lesser degree. In
14.04 we have a patch which does the modprobing for the "cpu" subsystem;
but reportedly this also affects drivers of other platforms, so let's
just backport that more generic upstream fix to cover all cases.

This can potentially cause a lot more attempts to load nonexisting
modules, and thus affect boot speed a bit. For 14.04 we have a builtin
kmod which is really fast to fail, so the impact should be negligible.
It might be measurable on 12.04 on some systems, but then again as we do
ship backported kernels on 12.04 and officially support them we don't
have much choice here.

Bug description:
  Udev version in Ubuntu 12.04 LTS Precise does not load all modules
  automatically. This is know bug in udev which was fixed more than one
  year ago in upstream project.

  Specially this bug cause that no module with cpu modalias is loaded
  for kernels >= 3.11.

  More info is on ML:
  http://lists.freedesktop.org/archives/systemd-devel/2013-July/012165.html

  Upstream patch which fixing this bug is simple and one-line:
  http://cgit.freedesktop.org/systemd/systemd/commit/?id=bf7f800f2b3e93ccd1229d4717166f3a4d3af72f

  Please backport this patch to Ubuntu 12.04 LTS. It should be simple as
  it is one-line patch and should not have any regressions. It is also
  in upstream udev project.
