[PATCH v2 3/5] KVM: x86: Add CPUID_7_1_EAX to the reverse CPUID table

From: Sean Christopherson
Date: Tue Dec 17 2019 - 16:32:48 EST


Add an entry for CPUID_7_1_EAX in the reserve_cpuid array in preparation
for incorporating the array in bit() build-time assertions, specifically
to avoid an assertion on F(AVX512_BF16) in do_cpuid_7_mask().

No functional change intended.
