Thanks, after applying Oliver's change, it's working, my concern post
at the beginning is to ask if
 Oliver's can resolve the issue:)
Now after testing Oliver's change, it's working, thanks
Sebastian,Oliver and Marc Zyngier:)

My test result now is:
```
/home/lygstate/work/qemu/build:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
/home/lygstate/work/qemu/build/qemu-system-aarch64
+ qemu-system-aarch64 -cpu host,aarch64=off -accel kvm -m 1024M -smp 1
-M virt,gic-version=3,midr=0x412fd050 -nographic -monitor none -serial
stdio -kernel /home/lygstate/work/debian/arm64-kvm-hello-world/bare-metal-aarch32-qemu/hello_world.elf
Get MIDR EL1 origin:0x410fd083
Set MIDR EL1:0x412fd050
Get MIDR EL1:0x412fd050
Hello World midr:0x412fd050
```
