    Subject[PATCH v13 14/16] include: pe.h: remove message[] from mz header definition
    Date
    message[] field won't be part of the definition of mz header.

    This change is crucial for enabling kexec_file_load on arm64 because
    arm64's "Image" binary, as in PE format, doesn't have any data for it and
    accordingly the following check in pefile_parse_binary() will fail:

    chkaddr(cursor, mz->peaddr, sizeof(*pe));
