Title:
  uio_pci_generic is not available in trusty kernel package for ppc64el

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Trusty:
  Fix Committed

Bug description:
  [Impact]
  uio_pci_generic is not enabled in linux kernel package for ppc64el while other architectures have it enabled.
  This is useful for things like DPDK.

  [Test Case]
  modprobe uio_pci_generic

  [Fix]
  CONFIG_UIO_PCI_GENERIC=m for common ubuntu config

  --

  Looking into git tree :

  ~/sources/pub/ubuntu.com/ubuntu-14.04-trusty$ git grep UIO_PCI_GENERIC debian.master/
  debian.master/config/amd64/config.common.amd64:CONFIG_UIO_PCI_GENERIC=m
  debian.master/config/arm64/config.common.arm64:CONFIG_UIO_PCI_GENERIC=m
  debian.master/config/armhf/config.common.armhf:CONFIG_UIO_PCI_GENERIC=m
  debian.master/config/i386/config.common.i386:CONFIG_UIO_PCI_GENERIC=m
  debian.master/config/powerpc/config.common.powerpc:CONFIG_UIO_PCI_GENERIC=m
  debian.master/config/ppc64el/config.common.ppc64el:# CONFIG_UIO_PCI_GENERIC is not set

  I can't find a reason why it would be disabled only for ppc64el and I
  can see that utopic enables it for all architectures (common
  configuration).

  Can we have it enabled ?
  This module is used by dpdk (for example).

  Thanks.
