At this point, I'm not going to get a pull request to Paolo before the normal
merge window.  I was hoping/planning to get some early pull requests to Paolo
this cycle so y'all could build on kvm/next directly, but that didn't happen.

I'd like to get at least a subset of this series in for 7.4.  If I'm reading
things correctly, all of the hacky changes I don't like are for the
kvm_create_max_vcpus_test and hardware_disable_test.  And as called out in the
final patch, "fixes" for PPC really should be ordered so that they land *before*
the tests are enabled.

Actually, better idea.  Limit patch 1 to just TEST_GEN_PROGS_COMMON, then for
the addon tests, bundle the "fix" with the PPC enablement.  AFAICT, except for
the kvm_create_max_vcpus changes, they're all pretty small, i.e. bundling the
PPC support with the "fix" shouldn't be too painful, and then we don't have to
worry about ordering.

As for kvm_create_max_vcpus and hardware_disable_test, drop them from the initial
enablement so we can get the core support landed, and tackle them as separate
series post-7.4.

As for actually landing this, the easiest thing at this point would probably be
for me to grab the patches in a dedicated topic branch that's based off the
kvm-x86/selftests branch at an appropriate point in time.  Alternatively, I
could provide a stable tag and someone else could grab the patches, but other
than it being a little weird taking PPC changes through kvm-x86, that's by far
the easiest approach since I'll be sending Paolo pull requests anyways and can
explain the dependencies and whatnot.

TL;DR: what if you post a slightly trimmed-down v6 and I take it through kvm-x86?
