This patch removes the unused EXPORT_SYMBOL(dump_trace) added on i386

By removing them before the final 2.6.19 we avoid the possibility of
people later whining that we removed exports they started using.

I exported it for systemtap so that they can stop using the broken
hack they currently use as unwinder.

Nack, dump_trace is nothing that should be export for broken out of tree
junk.

It is exported for systemtap not random broken out of tree junk, and the
result is a good deal prettier. Systemtap guys really ought to get their
stuff merged too, although how we merge a dynamic module writing tool I'm
not so sure ?

As you all know SystemTap uses kprobes and relayfs as the basis which are already merged into the mainline. We are looking at all the other pieces of SystemTap that can be merged to mainline but as Alan mentioned it is not easy and obvious. We think we can merge transport part of the runtime, here is the initial patch under review in this thread

We are open for other suggestions as well.

bye,
