Does somebody who's already reviewed the patch want to summarize what the effects on devices are -- i.e. what calls the device's read/write methods used to get if the guest did an unaligned access, including an unaligned access half off-the-end of the memory region, and what calls the read/write methods get after the patch ? The patch's commit message doesn't really describe what it's doing... thanks -- PMM
