SB600 claims it can do 64bit DMA but it can't.  Disable it.

If you have a controller with one channel disabled and unmapped the new
iomap code blindly tries to iomap unconfigured BARs. Later on the code
does the right thing and checks for unmapped bars but it is done in the
wrong order

Reorder the checks and make the iomap conditional

Tejun: I think the code below is now correct but would appreciate you
giving it a review.

A small number of SiS setups require special handling (not many judging
by how long this dumb bug survived). A couple of Fedora 7 devel testers
hit an Oops on pata_sis loading which is caused by terminal confusion
between chipset as 'the chipset we have found' and chipset as 'array
iterator'

* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev:
  libata: Limit ATAPI DMA to R/W commands only for TORiSAN DVD drives (take 3)
  libata: Limit max sector to 128 for TORiSAN DVD drives (take 3)
  libata: Clear tf before doing request sense (take 3)
  libata: reorder HSM_ST_FIRST for easier decoding (take 3)
  libata bugfix: preserve LBA bit for HDIO_DRIVE_TASK
  2.6.21 fix lba48 bug in libata fill_result_tf()

This adds some NCQ blacklist entries taken from the Silicon Image 3124/3132
Windows driver .inf files. There are some confirming reports of problems
with these drives under Linux (for example http://lkml.org/lkml/2007/3/4/178)
so let's disable NCQ on these drives.

 [ I'm personally starting to wonder whether we shouldn't disable NCQ by
   default, and perhaps have a white-list. There seems to be a *lot* of
   drives that do this wrong..   - Linus ]
