This is against master and doesn't depend on or conflict with anything
that's in Avi's branch. (I needed this because I've just rebased qemu-linaro
on master and one of the omap3 boards connects an smc91c111 up to the
omap_gpmc, which means it needs to be able to expose a MemoryRegion*.)

Thanks, applied to memory/queue.  If you need this in soon, feel free to 
ask Anthony to merge it.
