ppc patch queue 2016-07-01

Browse source 
Here's the current ppc patch queue.  This is a fairly large batch,
 containing:
     * A number of further preliminary patches towards full hypervisor
       mode emulation
     * Some further fixes / cleanups for the recently merged device_add
       based CPU hotplug
     * Preliminary patches towards supporting a native (rather than
       paravirtualized) XICS device.  This will be needed to emulate a
       physical Power machine, including hypervisor capabilities
     * Assorted bug fixes
