-qemu-system-x86_64: Linux kernel warning when CONFIG_NUMA_EMU is enabled
-Description of problem:
-When Linux kernel is run on qemu 6.2, it prints a warning when `NUMA_EMU` is used. When the same kernel is run on qemu 6.1.1 (`54e1f5be86dd11744e45da8be6afad01d01d59e7`) or earlier, no such warning is printed.

-```
-Steps to reproduce:
-1. Check out the Linux kernel:
-```
-git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
-cd linux-stable
-git checkout v5.16.9
-```
-2. Generate the configuration file:
-```
-make defconfig
-./scripts/config -e NUMA_EMU -e CMDLINE_BOOL --set-str CMDLINE "numa=fake=2 panic_on_warn=1" -d CONFIG_CMDLINE_OVERRIDE
-```
-3. Build the kernel
-```
-make -j32
-```
-4. Run qemu and wait for a couple of seconds:
-```
-./qemu-system-x86_64 -m 4G -smp 2 -kernel ~/linux-stable/arch/x86/boot/bzImage -append "console=ttyS0 root=/dev/sda earlyprintk=serial" -enable-kvm -nographic -snapshot
-```
-Additional information:
-With explicit NUMA configuration, it boots fine:
-```
-./qemu-system-x86_64 -m 4G -smp 2 -object memory-backend-ram,size=8G,id=m0 -numa node,cpus=0-1,nodeid=0,memdev=m0 -kernel ~/linux-stable/arch/x86/boot/bzImage -append "console=ttyS0 root=/dev/sda earlyprintk=serial" -enable-kvm -nographic -snapshot
-```
-
-On the host machine:
