'.rept' directive
Hi Heiko,
FYI, the error/warning still remains.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: e8f60cd7db24f94f2dbed6bec30dd16a68fc0828
commit: 4afeb670710efa5cd5ed8b1d9f2d22d6ce332bcc s390/alternatives: use instructions instead of byte patterns
date: 10 months ago
config: s390-randconfig-r004-20230110
