This entire file is also very specific to an architecture. Couldn't it
be put somewhere in arch/x86_64 and not in drivers?

I know that this is all currently focused on Intel and AMD
virtualization platforms, but could you split out the x86_64 specific
stuff and make the rest more generic. Perhaps in the future this will
make it easier for other platforms to use this code as well.

We're already doing some splitting since Intel and AMD have incompatible extensions for doing this. The result however will still be x86 (-64 and i386) specific.

It's hard to do a generic approach when developing it new, but if you
don't think about that now, it will be magnitudes larger in difficulty
to make generic when this is all done.

I don't know enough about ppc and ia64 virtualization for that. Perhaps someone would like to comment.
