uio_pci_generic is not available in trusty kernel package for ppc64el

[David Marchand]

[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.

Looks like everything 3.13+ has CONFIG_UIO_PCI_GENERIC=m except ppc64el.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Problem fixed on both "Linux 3.13.0-63-generic" and "Linux 3.16.0-48-generic" on Trusty.

Thanks!
