# gpg: Signature made Mon 19 Mar 2018 20:07:14 GMT
# gpg:                using RSA key 2807936F984DC5A6

# 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
