Barriers in qemu-barrier.h should not be x86 specific
qemu-barrier.h contains a few macros implementing memory barrier
primitives used in several places throughout qemu. However, apart
from the compiler-only barrier, the defined wmb() is correct only for
x86, or platforms which are similarly strongly ordered.
This patch addresses the FIXME about this by making the wmb() macro
arch dependent. On x86, it remains a compiler barrier only, but with
a comment explaining in more detail the conditions under which this is
correct. On weakly-ordered powerpc, an "eieio" instruction is used,
again with explanation of the conditions under which it is sufficient.
On other platforms, we use the __sync_synchronize() primitive,
available in sufficiently recent gcc (4.2 and after?). This should
implement a full barrier which will be sufficient on all platforms,
although it may be overkill in some cases. Other platforms can add
optimized versions in future if it's worth it for them.
Without proper memory barriers, it is easy to reproduce ordering
problems with virtio on powerpc; specifically, the QEMU puts new
element into the "used" ring and then updates the ring free-running
counter. Without a barrier between these under the right
circumstances, the guest linux driver can receive an interrupt, read
the counter change but find the ring element to be handled still has
an old value, leading to an "id %u is not a head!\n" error message.
Similar problems are likely to be possible with kvm on other weakly
ordered platforms.

virtio: Use global memory barrier macros
The virtio code uses wmb() macros in several places, as required by the
SMP-aware virtio protocol. However the wmb() macro is locally defined
to be a compiler barrier only. This is probably sufficient on x86
due to its strong storage ordering model, but it certainly isn't on other
platforms, such as ppc.
In any case, qemu already has some globally defined memory barrier macros
in qemu-barrier.h. This patch, therefore converts virtio.c to use those
barrier macros. The macros in qemu-barrier.h are also wrong (or at least,
safe for x86 only) but this way at least there's only one place to fix
them.
