Packed attribute for the union looks redundant.

Can mshv_handler be defined as a weak symbol doing nothing instead
of defining it a null pointer?
This should allow to simplify this code and get rid of
hv_setup_mshv_handler, which looks redundant.

writing the
HV_X64_MSR_TSC_INVARIANT_CONTROL register. Not all guests will have this
privilege and the hypervisor will automatically opt-in certain types of
guests (e.g. EXO partitions) to invariant TSC, but this functionality is
unrelated to the TSC reliability.
