Linus Torvalds 14bed9bc81 - Map the SNP calling area pages too so that OVMF EFI fw can issue SVSM 
calls properly with the goal of implementing EFI variable store in the
   SVSM - a component which is trusted by the guest, vs in the firmware, which
   is not
 
 - Allow the kernel to handle #VC exceptions from EFI runtime services
   properly when running as a SNP guest
 
 - Rework and cleanup the SNP guest request issue glue code a bit
