I found this trying to test out the upstream SEV secret injection on an
AMD rome system.  However, I rebuilt the OvmfPkgX64 (still on a rome
system) just to check.  I get a boot loop here if I leave this commit
unreverted:

InstallProtocolInterface: BC62157E-3E33-4FEC-9920-2D3B36D750DF 7F1AD918
ProtectUefiImageCommon - 0x7F1AD2C0
  - 0x000000007F068000 - 0x000000000000FCC0
Paging: added 512 pages to page table pool
CurrentPagingContext:
  MachineType   - 0x8664
  PageTableBase - 0x7F801000
  Attributes    - 0xC0000006
SecCoreStartupWithStack(0xFFFCC000, 0x820000)

If I revert this commit, it will boot up normally.

The memory specification for qemu-kvm I'm using is

-m 4096M,slots=5,maxmem=30G

but reducing it to under 4GB doesn't help
