QEMU incorrectly validates FEAT_SVM feature flags against GET_SUPPORTED_CPUID even if SVM features are being masked out by cpu_x86_cpuid(). This can make QEMU print warnings on most AMD CPU models, even when SVM nesting is disabled (which is the default). This bug was never detected before because of a Linux KVM bug: until Linux v5.6, KVM was not filtering out SVM features in GET_SUPPORTED_CPUID when nested was disabled. This KVM bug was fixed in Linux v5.7-rc1, on Linux commit a50718cc3f43 ("KVM: nSVM: Expose SVM features to L1 iff nested is enabled"). Fix the problem by adding a CPUID_EXT3_SVM dependency to all FEAT_SVM feature flags in the feature_dependencies table.
