AMD64: LDTSTOP vs hard reset

In addition to lowering the number of resets it would also be possible
to use an LDTSTOP (as I implemented it in older versions of the CVS)
at least when doing the hypertransport link changes.
I know that this does not work with some preproduction CPUs, but I don't
think that would really matter. BUT: Could we get rid of all CPU resets
when doing an LDTSTOP assertion (It's a lot quicker than a hard reset)
or would we still need to reset the CPU for some other reasons?
