Hi,

While running kernel self tests on ppc64, tm/tm-signal-context-chk-vsx
tests fails with Oops message. 

I was able to reproduce only twice out of 20 runs on next-20170324 only.
so it is difficult to bisect the commit causing the issue.

Can you try mainline as of this commit:

605df8d674ac ("selftests/powerpc: Replace stxvx and lxvx with stxvd2x/lxvd2x")

https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?id=605df8d674ac65e044a0bf4998b28c2f350b7f9e

cheers
