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)); Signed-off-by: AKASHI Takahiro <takahiro.akashi@...aro.org> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@...aro.org> Cc: David Howells <dhowells@...hat.com> Cc: Vivek Goyal <vgoyal@...hat.com> Cc: Herbert Xu <herbert@...dor.apana.org.au> Cc: David S.
