Bug description:
[Impact]
* Certain Guest features (SPRS) of power8 isa are not working
* This is part of the ongoing LTS HW exploitation and a fixup to some
verification tests at the same time.
[Test Case]
* 1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests.sh -v
[Regression Potential]
* The changes are ppc only and provided by IBM so the potential risk is
retained to the owner of the Area.
Further if these registers are not used they do nothing, so in most
cases it will be a nop.
OTOH the changes are rather huge (in terms of LOC) so there is some
risk left.
[Other Info]
* n/a

The sprs test has failed on ppc64le
This issue can be spotted on Zesty and Xenial. There is no history for this
test on Artful
