Subject: physmap warning on next-20210921
Hi,
When I'm building an allmodconfig kernel (arm64) with
KCONFIG_ALLCONFIG=arch/arm64/configs/defconfig all the bootselftests
turned off also.
I see the following warning.

This is my qemu cmd line:
qemu-system-aarch64 --enable-kvm -cpu cortex-a53 -kernel
Image-20210921-3.gz -serial stdio -monitor none -nographic -m 2G -M
virt -fsdev local,id=root,path=/srv/kvm/tmp/stretch/arm64,security_model=none,writeout=immediate
-device virtio-rng-pci -device
virtio-9p-pci,fsdev=root,mount_tag=/dev/root -append "root=/dev/root

earlycon=pl011,0x9000000 initcall_debug softlockup_panic=0
security=none kpti=no"
I did not expect the physmp-flash device to be used at all.
Does anyone see what might be wrong here ?
Cheers,
Anders
