Merge remote-tracking branch 'remotes/ehabkost/tags/machine-next-pull-request' into staging
Machine and x86 queue, 2018-03-19
* cpu_model/cpu_type cleanups
* x86: Fix on Intel Processor Trace CPUID checks
# gpg: Signature made Mon 19 Mar 2018 20:07:14 GMT
# gpg: using RSA key 2807936F984DC5A6
# gpg: Good signature from "Eduardo Habkost <ehabkost@redhat.com>"
# Primary key fingerprint: 5A32 2FD5 ABC4 D3DB ACCF D1AA 2807 936F 984D C5A6
* remotes/ehabkost/tags/machine-next-pull-request:
i386: Disable Intel PT if packets IP payloads have LIP values
cpu: drop unnecessary NULL check and cpu_common_class_by_name()
cpu: get rid of unused cpu_init() defines
Use cpu_create(type) instead of cpu_init(cpu_model)
cpu: add CPU_RESOLVING_TYPE macro
tests: add machine 'none' with -cpu test
nios2: 10m50_devboard: replace cpu_model with cpu_type
