Objtool requires the use of a DRAP register while aligning the stack. Since a DRAP register is a gcc concept and we are notoriously low on registers in the crypto code, it's not worth the effort to mimic gcc generated stack realignment. We simply silence the warning by adding the offending object files to OBJECT_FILES_NON_STANDARD. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Attila Fülöp <attila@fueloep.org> Closes #6950 Closes #11914
