Subject: [PATCH] KVM: x86: Add CPUID_7_1_EAX to the reverse CPUID table
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.
