+qemu-system-x86_64 segfaults in iotlb_to_section() on riscv64
+Description of problem:
+QEMU segfaults when booting up the Arch Linux x86_64 installation ISO. The ISO could be downloaded from https://geo.mirror.pkgbuild.com/iso/2023.09.01/archlinux-2023.09.01-x86_64.iso or any other Arch Linux mirrors.
+
+The crash often happens after "Probing EDD...". It's more reliably reproducible with higher `-smp` numbers, and may hang with "rcu_preempt detected stalls" without the -smp option.
+Additional information:
+I have reproduced the same issues with different RISC-V hardware, including SG2042 and TH1520.
+
+Errors:
