Bug#758620: linux-image-3.2.0-4-powerpc64: please enable CONFIG_VSX in the powerpc64 flavours

Package: linux
Version: 3.2.0-4
Severity: minor

Hi,

I was trying to test some VSX code in the partch.debian.org
powerpc/powerpc64 porterbox and while VSX support was enabled in the
compiler, it was not enabled in the kernel. Since it's
required/recommended to use official kernels in Debian porterboxes, I
was advised to send a bug report to the kernel package to have VSX
enabled in the stable (but also the unstable) PowerPC64 kernel as well.
For that matter, the ppc64el porterbox, pastel.debian.net does have VSX
enabled, but I would like to test both big and little endian VSX code.

Regards

Konstantinos

Setting CONFIG_VSX=y on the wheezy kernel triggers an ABI change
affecting almost all symbols, so I think this change is unlikely to
happen. If VSX needs to be activated on a wheezy machine, the bpo kernel
would do it. And this problem will be fixed for jessie as the 3.14
kernel already has CONFIG_VSX=y.
