Borislav, please take the whole series via the tip tree if possible.
That's perhaps the easiest thing for both of us because the rest of the
series depends on this patch. Or else I will have to base hyperv-next on
the tip tree once you merge this patch.

Let me know what you think.

You'll be able to simply merge the tip/x86/sev branch which will have it
and then base everything ontop.

However, there's still a question open - see my reply to Michael.

Hi Boris:
I just sent out v9 version and compile hv ghcb related functions
when CONFIG_AMD_MEM_ENCRYPT is selected. The sev_es_ghcb_hv_call() stub
is not necessary in the series and remove it. Please have a look and
give your ack if it's ok. Then Wei can merge it through Hyper-V next
branch.

Thanks.
