[Qemu-devel] [PATCH 05/20] target-i386: convert 'check' and 'enforce' to static properties

[Igor Mammedov]

* additionally convert check_cpuid & enforce_cpuid to bool and make them
  members of CPUX86State
* make 'enforce' feature independent from 'check'

v2:
  - put check_cpuid and enforce_cpuid into X86CPU
