While Linux/KVM is only LE, the arch doesn't prohibit S-mode being
configured to use BE memory accesses, so I kept the conversions. They
at least provide some self-documenting of the code. The biggest
problem with them, though, is that I didn't use __le64 types and now
sparse is yelling at me. I patched that this morning, but didn't get
a chance to post yet. I could instead rip out the conversions to
quiet sparse, if that would be preferred.

Thanks,
