bisecting kernel from the 6.5.0-41 to latest master-next, the patch "x86/boot: Omit compression buffer from PE/COFF image memory footprint" also causes fail to boot up.

    x86/boot: Omit compression buffer from PE/COFF image memory footprint

    BugLink: https://bugs.launchpad.net/bugs/2061814

    commit 8eace5b3555606e684739bef5bcdfcfe68235257 upstream.

    Now that the EFI stub decompresses the kernel and hands over to the
    decompressed image directly, there is no longer a need to provide a
    decompression buffer as part of the .BSS allocation of the PE/COFF
    image. It also means the PE/COFF image can be loaded anywhere in memory,
    and setting the preferred image base is unnecessary. So drop the
    handling of this from the header and from the build tool.
