This changeset revolves around the fact that all the SiS controllers have
the same enable bits, but differing cable detection methods. Previously
that meant each type had its own error_handler methods. Instead we can
now implement different ->cable_detect methods and share a single
error_handler which does the filtering by enable bits.

In addition we had some auto const arrays that should be static const. I'm
not sure if gcc already treats them intelligently but adding the static
will make sure.

2.6.21-rc has horrible problems with libata and PATA cable types (and
thus speeds). This occurs because Tejun fixed a pile of other bugs and
we now do cable detect enforcement for drive side detection properly.

Unfortunately we don't do the process around cable detection right. Tejun
identified the problem and pointed to the right Annex in the spec, this patch
implements the rest of the needed changes.

We add a ->cable_detect() method called after the identify
sequence which allows a host to do host side detection at this point
should it wish, or to modify the results of the drive side identify.

This separate ->cable_detect method also cleans up a lot of code because
many drivers have their own error_handler methods which really just set
the cable type.

If there is no ->cable_detect method the cable type is left alone so a
driver setting it earlier (eg because it has the SATA flags set or
because it uses the old error_handler approach) will still do the right
thing (or at least the same thing) as before.

This patch simply adds the cable_detect method and helpers it doesn't use
them but other follow up patches will (ie Adrian please don't submit
patches to unexport them ;))

The chips covered by sata_mv have a 32-bit DMA boundary they must not
cross, not a 64K boundary.  We are merely limited to a 64K maximum
segment size.  Therefore, the DMA scatter/gather table fill code can be
greatly simplified, and we need not cut in half the S/G table size as
reported to the SCSI layer.

Also, the driver forget to turn on 64-bit DMA at the PCI layer.  All
other data structures (both hardware and software) have been prepped for
64-bit PCI DMA.  It was simply never turned on.  <fingers crossed> let's
see if it still works...

  sis900: Allocate rx replacement buffer before rx operation
  usb-net/pegasus: simplify carrier detection

Just found a hole in my last patch.  It was reported to me that shortly after we
integrated this patch.  The report was of an oops that took place inside of
netif_rx when using the sis900 driver.  Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame.  The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring.  So if you receive frames fast enough the skb being processed by
the network stack can get corrupted.  The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP.  I'll post test results when I hear
them, but I think this is a pretty straightforward fix.  It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.
