+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.

+`hw/arm/virt.c`
+```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.
