[Qemu-devel] [PATCH 4/9] target-i386: check/enforce: Do not ignore "hypervisor" flag |

We don't need any hack to ignore CPUID_EXT_HYPERVISOR anymore, because
kvm_arch_get_supported_cpuid() now set CPUID_EXT_HYPERVISOR properly.
So, this shouldn't introduce any behavior change, but it makes the code
simpler.

My goal is to eliminate the check_feat field completely, as
kvm_arch_get_supported_cpuid() should now really return all the bits we
can set on all CPUID leaves.
