Is this bug still present?

I can see a fix to VSX handling in the kernel that went into mainline
just after this, and then into 4.9.45:

commit 5a69aec945d27e78abac9fd032533d3aaebf7c1e
Author: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date:   Wed Aug 16 16:01:14 2017 +1000

    powerpc: Fix VSX enabling/flushing to also test MSR_FP and MSR_VEC    

Ben.
