Can you give me more details on the qemu configuration so I could try
to reproduce it?

qemu-system-arm -M vexpress-a9 -kernel arch/arm/boot/zImage -no-reboot \
-initrd rootfs-armv5.cpio -m 128 \
--append "rdinit=/sbin/init console=ttyAMA0,115200" \
-dtb arch/arm/boot/dts/vexpress-v2p-ca9.dtb \
-nographic -monitor null -serial stdio

using multi_v7_defconfig will hang nicely with your patch applied,
and boot as expected without. This was with qemu v7.0, but I am
sure older qemu versions will show the same behavior. The initrd
used should not matter, but you'll find it at
https://github.com/groeck/linux-build-test/blob/master/rootfs/arm-v7/rootfs-armv5.cpio.gz
