When running multiple VMs with GPU passthrugh, both VMs will crash
unless all virtual disks are on the same physical volume as root, likely
on all X58 chipset motherboards. I've tested with 3.
Expected Behavior: No Crash
Result: Both VMs GPU drivers fail and the guest OS a

With this microbenchmark we can measure the overhead of emulating atomic

The benchmark spawns $n threads, each performing $o atomic ops (additions)

Rather than using helpers for physical accesses, use a mmu index.

Allow qemu to build on 32-bit hosts without 64-bit atomic ops.
Even if we only allow 32-bit hosts to multi-thread emulate 32-bit
guests, we still need some way to handle the 32-bit guest using a
64-bit atomic operation. Do so by dropping back to single-step.

Changes since v2:
* Fix build for 32-bit host without 64-bit atomics.
Tested with --extra-cflags='-march=-i486'.
This is patch 15, which might ought to get folded back into
patch 13 for bisection, but is ugly for review.
* Move a lot of stuff out of softmmu_template.h, and into cpu
Allows Int128 to be used more generally, rather than having to
begin with 64-bit inputs and accumulate.

If backend(such as dpdk) lack this feature,
don't assume it and mark it in vring_enable.
Or we may fail in vhost_net_start,
then we can't use vhost net.
This will bring compat issue with old version backend.
