+mmap-ing more than 1GB of files fails on v8.0 of QEMU, but works on older version
+Description of problem:
+Trying to run an application using QEMU user mode for an ARM binary.  My host system is Ubuntu 22.04 based.  The v6.2 from Ubuntu repos is able to mmap files that contain more than 1GB of address space, but version 8.0 that I compiled will not.
+
+I created a repo with a readme, and a simple application that you can use to demonstrate the problem:
+https://github.com/mwales/qemu_mmap_test
+
+Example application simply takes a list of files, mmaps the entire file into memory, and then computes a checksum of the file data.  Once the file(s) sizes exceed around 1GB, the mmap calls will fail because the memory from 0x00000000 - 0x40000000 has been exhausted.
+Steps to reproduce:
+1. Compile test application that mmaps entire files
+2. Create 5 256MB test files
+3. Run the program tell it to mmap all the files.  The first 3 files succeed, but the 4th when run gets a -1 returned from mmap.
+Additional information:
+Lots of details on my github writeup and a demo of the bug in question.
+
+It seems that this 1GB limit is an artifact of where QEMU loaded the original ELF binary at (0x40000000).  I've also been playing around with moving that address using the -B 0x80000000 option, but I've encountered other problems doing that.  As I diagnose that, I figured I would write up this report on what I've seen so far incase I'm doing something dumb / creating a bad build or something.

+CVE-2017-7471 repeated?
+
+In the hw/9pfs/9p-proxy.c file I can see the following which is changed because of CVE-2017-7471 in the hw/9pfs/9p-local.c. I might be wrong but I guess that should be changed as well.

+migration state save/load of sdcard device is broken
+
+I'm having different issues trying to have QEMU snapshots working using qemu-system-arm with vexpress-a15 board.
+
+In this opportunity, I'm trying the git master head version:
+# git rev-parse HEAD
+af352675efb7e92a1f5f6461a042a12015ab3d12
+
+$ /usr/local/bin/qemu-system-arm -kernel kernel/vmlinuz-4.10.0-42-generic -initrd kernel/initrd.img-4.10.0-42-generic -M vexpress-a15 -m 2048 -append 'root=/dev/mmcblk0 rootwait console=tty0' -sd vexpress-4G.qcow2 -dtb device-tree/vexpress-v2p-ca15-tc1.dtb  
+audio: Could not init `oss' audio driver
+
+Later on, when the machine finishes booting I savevm ss and quit. However, when I try to restore it, I have that Missing section footer error:
+
+$ /usr/local/bin/qemu-system-arm -kernel kernel/vmlinuz-4.10.0-42-generic -initrd kernel/initrd.img-4.10.0-42-generic -M vexpress-a15 -m 2048 -append 'root=/dev/mmcblk0 rootwait console=tty0' -sd vexpress-4G.qcow2 -dtb device-tree/vexpress-v2p-ca15-tc1.dtb  -loadvm ss
+audio: Could not init `oss' audio driver
+qemu-system-arm: Missing section footer for sd-card
+qemu-system-arm: Error -22 while loading VM state
+
+
+OS: Ubuntu 16.04.3 LTS (xenial)
+
+$ gcc --version
+gcc (Ubuntu 5.4.0-6ubuntu1~16.04.5) 5.4.0 20160609
+
+I've also tried a different ./configure line, explicitly enabling some of the features, i.e. smartcard, with the same results:
+
+./configure '--disable-user' '--enable-system' '--enable-linux-user' '--enable-modules' '--enable-linux-aio' '--audio-drv-list=pa' '--enable-attr' '--enable-brlapi' '--enable-virtfs' '--enable-cap-ng' '--enable-curl' '--enable-fdt' '--enable-gnutls' '--disable-gtk' '--disable-vte' '--enable-libiscsi' '--enable-curses' '--enable-smartcard' '--enable-rbd' '--enable-vnc-sasl' '--enable-seccomp' '--enable-spice' '--enable-libusb' '--enable-usb-redir' '--enable-xfsctl' '--enable-vnc' '--enable-vnc-jpeg' '--enable-vnc-png' '--enable-kvm' '--enable-vhost-net'
+
+How have I built it?
+# git clone git://git.qemu.org/qemu.git
+# cd qemu
+# git submodule update --init --checkout
+# make clean && ./configure --target-list=arm-softmmu && make -j8
+# sudo make install
+
+As a reference, and just in case these may be in some way related, I've just submitted another ticket for a different issue with snapshots using Ubuntu Qemu version (https://bugs.launchpad.net/qemu/+bug/1739371)
+
+Cheers,
+Gus
