Nitpick: we can probably have a 'static inline' for

  "npt_enabled && ms_hyperv.nested_features & HV_X64_NESTED_ENLIGHTENED_TLB"

e.g. 'hv_svm_enlightened_tlbflush()'
Makes sense, will do.
On a second thought, this function itself is small and just does this one check.
So, might not make sense to add one more function. I shall rather change this
function to be an inline.

Thanks,
