Bug Description
[Impact]
POWER7/POWER8 systems which have the VSX bit enabled by default may find themselves crashing with 'instruction exception' errors when booting.
[Test case]
- Install grub
- Boot the system
[Regression Potential]
VSX being disabled means another piece of software down the stack needs to re-enable it when necessary. This should be done by the kernel.

This is already fixed since Utopic (the patch comes from there); we only need to SRU it to Trusty.
