TSC_ADJUST handling should not be needed for guests running in Hyper-V.
For backward compatibility, turn it off only when built with CONFIG_HYPERV_VTL_MODE. This addresses an issue where the TSC_ADJUST runtime checks would conflict with restore_partition_time handling that would adjust the global TSC value using a Hyper-V hypercall.
