Merge remote-tracking branch 'afaerber/tags/qom-cpu-for-anthony' into staging
QOM CPUState refactorings
* Fix cpu_memory_rw_debug() breakage in s390x KVM
* Replace final CPUArchState in sysemu/kvm.h
* Introduce model subclasses for XtensaCPU
* Introduce CPUClass::gdb_num[_core]_regs
* Introduce CPUClass::gdb_core_xml_file
* Introduce CPUClass::gdb_{read,write}_register()
* Propagate CPUState further in gdbstub
