[Qemu-devel] [RFC 5/6] target-i386: Move kvm_features/hypervisor initialization to cpu_x86_find_by_name()

[Eduardo Habkost <ehabkost@redhat.com>]

Move the initialization to the cpu_x86_find_by_name(), inside the block
for predefined CPU models.

That code is not necessary for -cpu "host", because:

- kvm_features doesn't need to be set because kvm_cpu_fill_host()
  already sets all bits supported by the host.
- the CPUID_EXT_HYPERVISOR flag doesn't need to be manually set because
  kvm_arch_get_supported_cpuid() already sets it.
