  log: "Pull up following revision(s) (requested by manu in ticket #1380):\n\n\tsys/arch/x86/acpi/acpi_machdep.c:
    revision 1.27,1.28 (patch)\n\nAttempt to obtain ACPI RSDP from the hypervisor
    for Xen PV\nThere are three possible way of obtaining the ACPI RSDP\n\n- From
    Extended BIOS Data Area (EBDA) when kernel or Xen was booted from\n  BIOS bootstrap\n-
    From EFI SystemTable when kernel is booted from EFI bootstrap\n- When Xen is booted
    from EFI bootstrap, EBDA is not mapped, and EFI\n  SystemTable is not passed to
    the kernel. The only way to go is to\n  obtain ACPI RSDP trhough an hypercall.\n\nNote:
    EFI bootstrap support for booting Xen has not yet been committed.\n\nCast physical
    addresses via uintptr_t to ACPI_PHYSICAL_ADDRESS to deal\nwith all size variants
    of the types used here in different builds.\n"
