Generally all the patches in this series look fine to me but I have a
few questions...

So are these patches needed for ARM and/or Sparc?  Do we have any
reports of unaligned accesses from people working on those CPU
architectures?  I guess more to the point, do *we* have any ARM or Sparc
systems with which we can test?

Thanks,
