ppc patch queue for 2017-02-22

Browse source 
This pull request has:
    * Yet more POWER9 instruction implementations
    * Some extensions to the softfloat code which are necesssary for
      some of those instructions
    * Some preliminary patches in preparation for POWER9 softmmu
      implementation
    * Igor Mammedov's cleanups to unify hotplug cpu handling across
      architectures
    * Assorted bugfixes
 
 The softfloat and cpu hotplug changes aren't entirely ppc specific (in
 fact the hotplug stuff contains some pc specific patches).  However
 they're included here because ppc is one of the main beneficiaries,
 and the series depend on some ppc specific patches.

* remotes/dgibson/tags/ppc-for-2.9-20170222: (43 commits)
  hw/ppc/ppc405_uc.c: Avoid integer overflows
  hw/ppc/spapr: Check for valid page size when hot plugging memory
  target-ppc: fix Book-E TLB matching
  hw/net/spapr_llan: 6 byte mac address device tree entry
  machine: replace query_hotpluggable_cpus() callback with has_hotpluggable_cpus flag
  machine: unify [pc_|spapr_]query_hotpluggable_cpus() callbacks
  spapr: reuse machine->possible_cpus instead of cores[]
  change CPUArchId.cpu type to Object*
  pc: pass apic_id to pc_find_cpu_slot() directly so lookup could be done without CPU object
  pc: calculate topology only once when possible_cpus is initialised
  pc: move pcms->possible_cpus init out of pc_cpus_init()
  machine: move possible_cpus to MachineState
  hw/pci-host/prep: Do not use hw_error() in realize function
  target/ppc/POWER9: Direct all instr and data storage interrupts to the hypv
  target/ppc/POWER9: Adapt LPCR handling for POWER9
  target/ppc/POWER9: Add ISAv3.00 MMU definition
  target/ppc: Fix LPCR DPFD mask define
  target-ppc: Add xscvqpudz and xscvqpuwz instructions
  target-ppc: Implement round to odd variants of quad FP instructions
  softfloat: Add float128_to_uint32_round_to_zero()
