-qemu-system-arm: unable to use LPAE
-Description of problem:
-Failed to run qemu: qemu-system-arm: Addressing limited to 32 bits,
-but memory exceeds it by 1073741824 bytes
-Steps to reproduce:
-1. ./configure --target-list=arm-softmmu
-2. make
-3.
-./qemu-system-arm \
--machine virt,highmem=on \
--cpu cortex-a15 -smp 4 \
--m 4096 \
--kernel ./zImage \
--drive id=disk0,file=./rootfs.ext4,if=none,format=raw \
--object rng-random,filename=/dev/urandom,id=rng0 \
--device virtio-rng-pci,rng=rng0 \
--device virtio-blk-device,drive=disk0 \
--device virtio-gpu-pci \
--serial mon:stdio -serial null \
--nographic \
--append 'root=/dev/vda rw mem=4096M ip=dhcp console=ttyAMA0 console=hvc0'
-Additional information:
-We set physical address bits to 40 if ARM_FEATURE_LPAE is enabled. But ARM_FEATURE_V7VE also implies ARM_FEATURE_LPAE as set later in arm_cpu_realizefn.
-
-We should add condition for ARM_FEATURE_V7VE, otherwise we would not be able to use highmem larger than 3GB even though we have enabled highmem, since we would fail and return right from machvirt_init. 
-
-I have already made a patch to fix this issue.

-```c
-        if (object_property_get_bool(cpuobj, "aarch64", NULL)) {
-            pa_bits = arm_pamax(armcpu);
-        } else if (arm_feature(&armcpu->env, ARM_FEATURE_LPAE)) {
-        } else if (arm_feature(&armcpu->env, ARM_FEATURE_LPAE)
-                || arm_feature(&armcpu->env, ARM_FEATURE_V7VE)) {
-            /* v7 with LPAE */
-            pa_bits = 40;
-        } else {
-```
-
-After applying the patch, I can make sure that the pa_bits has already been set to 40, but qemu hangs later. By bisecting I found if the following commit is reverted qemu can boot up successfully..

-It can't be quickly determined what's going on here at my side. Maybe the author can help give some hints. Thanks.
