[SRU][Xenial][PATCH 0/1] Fixes for LP#1714420

[Daniel Axtens]

[SRU Justification]

[Impact]
ppc64le system OOPSes shortly after boot when KVM guests are started.

[Fix]
Cherry-pick patch e47057151422a67ce08747176fa21cb3b526a2c9

[Testcase]
Tested at IBM - boot a machine with a KVM guest configured to start at
boot. Without this patch, observe OOPS, with this patch, observe no
OOPS.

[Regression Potential]
Patch is contained in arch/powerpc; so regression potential limited to
that arch. Patch accepted to kernel stable trees, suggesting others
also believe it to be of low risk.

[Notes]
Not applicable to Zesty (as far as I can tell) as Zesty hasn't pulled
in 46a704f8409f7 ("KVM: PPC: Book3S HV: Preserve userspace HTM state
properly")
