[Patch v3 05/13] KVM: selftests: Convert hyperv_features test to using KVM_X86_CPU_FEATURE()
From: Vipin Sharma
Date: Mon Dec 05 2022 - 14:15:42 EST
From: Vitaly Kuznetsov <vkuznets@xxxxxxxxxx>
hyperv_features test needs to set certain CPUID bits in Hyper-V feature
leaves but instead of open coding this, common KVM_X86_CPU_FEATURE()
infrastructure can be used.
