Tom,
why this cannot be done as today's code in ExitBS callback?
Because it should be done after interrupt is disabled?

> Additionally, the AP stack must be located where it can be accessed
> in real mode.
> - Once the AP is in real mode it will transfer control to the
> destination specified by the OS in the SEV-ES AP Jump Table. The
> SEV-ES AP Jump Table address is communicated to the OS using the BSP
> GHCB MSR.
