Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.7-20160617' into staging

ppc patch queue for 2016-06-17

Here's the current accumulated set of spapr, ppc and related patches.
* The big thing in here is CPU hotplug for spapr
- This includes a number of acked generic changes adding new
infrastructure for hotplugging cpu cores
* A number of TCG bug fixes are also included
* This adds a new testcase to make it harder to accidentally break
Macintosh (and other openbios) platforms

spapr: CPU hot unplug support

Remove the CPU core device by removing the underlying CPU thread devices.
Hot removal of CPU for sPAPR guests is achieved by sending the hot unplug
notification to the guest. Release the vCPU object after CPU hot unplug so
that vCPU fd can be parked and reused.

spapr: convert boot CPUs into CPU core devices

Introduce sPAPRMachineClass.dr_cpu_enabled to indicate support for
CPU core hotplug. Initialize boot time CPUs as core deivces and prevent
topologies that result in partially filled cores. Both of these are done
only if CPU core hotplug is supported.

Note: An unrelated change in the call to xics_system_init() is done
in this patch as it makes sense to use the local variable smt introduced
in this patch instead of kvmppc_smt_threads() call here.

TODO: We derive sPAPR core type by looking at -cpu <model>. However
we don't take care of "compat=" feature yet for boot time as well
as hotplug CPUs.
