Hi all,

I am trying to boot a Xen guest using the latest EDK2 master (cce9d76358
"BaseTools: Allow empty value for HiiPcd in Dsc"), GRUB and Linux 5.0-rc2.

The last code executed by Linux is when installing the virtual address
map in the EFI stub and then it seems to get stuck. I don't have much
information from the console:

The bisector pointed to the following commit:

commit 2f4a5a9f4c17ed88aaa3114d1e161e42cb80a9bf
Author: Dandan Bi <dandan.bi@intel.com>
Date:   Thu Jan 3 15:31:23 2019 +0800

    MdePkg/BasePeCoffLib: Add more check for relocation data
    
    REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1426
    
    V2:
    (1) Add NULL pointer check for the input parameters
    (2) Add check for the "Adjust" value before applying fix ups.
    
    In function PeCoffLoaderRelocateImageForRuntime, it doesn't
    do much check when do relocation. For API level consideration,
    it's not safe enough.
    So this patch is to replace the same code logic with function
    PeCoffLoaderImageAddress which will cover more validation.

Any ideas what could have gone wrong?
