charset="utf-8" Commit bbf3810f2c4f ("target/i386: Fix conditional CONFIG_SYNDBG enablement") broke !CONFIG_SYNDBG builds as hyperv_syndbg_query_options() is missing there. The idea probably was that as "hv-syndbg" is now under '#ifdef CONFIG_SYNDBG', hyperv_feat_enabled(cpu, HYPERV_FEAT_SYNDBG) cannot be true anyway. It would have been possible to add a stub for hyperv_syndbg_query_options() instead of resurrecting '#ifdef CONFIG_SYNDBG' but avoiding HV_X64_MSR_SYNDBG_OPTIONS altogether instead of zeroing it when !CONFIG_SYNDBG seems preferable.
