This addresses two items, which are unlikely to be hit if we
trust drivers.
The first is moving a memory barrier below where the vmerged SG count
is passed back, but before the list is set to end. If those
instructions were reordered, there could be an issue in iommu_unmap_sg().
The second is making sure we terminate the list on the failure case of
iommu_map_sg(). If a driver does not look at the failure return code,
it could pass a ill-formed SG list to iommu_unmap_sg().

You can't boot a kdump kernel via OF, not reliably anyway, the kernel being at
32 MB conflicts with the zImage wrapper etc. and it blows up.
It's trivial to check in prom_init though, and this is early enough that we can
actually drop back to OF where a reset-all will get you going again, which is
kinda nice. I think this should go in for 2.6.16.

To prevent problems later in boot, make sure we don't create zero-size lmb
regions.
I've checked all the callers, and at the moment no one should ever hit this.
All callers use a constant size, or they check the computed size before they
call us.

In prom.c we run finish_node() on allnodes twice. The first time we just
calculate how much memory we'll need, the second time we do the actual work.
If the calculation stage determines that we need 0 bytes, then we should skip
the lmb allocation. Although an alloc of zero will work, it has been seen to
lead to a BUG_ON() in reserve_bootmem() on at least one machine.

The last two 8MB TLB entries are being incorrectly set by initial_mmu on 8xx.

The at76c651 and tda80xx frontends are currently completely unused, IOW
their only effect is making the kernel larger for people accitentially
