[Qemu-devel] [PATCH v2 1/2] spapr: introduce SPAPR_MACHINE_NOASSERT()

A spapr-cpu-core device can only be plugged into a pseries machine. This is checked in spapr_cpu_core_realize() with object_dynamic_cast() instead of the usual SPAPR_MACHINE() macro because we don't want QEMU to abort. This patch moves the gory details to a SPAPR_MACHINE_NOASSERT() macro that

The modern bar is accessed now via yet another address space created just for that purpose and it does not really need FlatView and dispatch tree as it has a single memory region so it is just a waste of memory. Things get even worse when there are dozens or hundreds of virtio-pci devices - since
