This patch adds support to the fschmd driver for reading the voltage scaling
factors from BIOS DMI tables, as specified in the Siemens datasheet.

While it is possible to force SMBus-based hardware monitoring chip
drivers to drive a not officially supported device, we do not have this
possibility for Super-I/O-based drivers. That's unfortunate because
sometimes newer chips are fully compatible and just forcing the driver
to load would work. Instead of that we have to tell the users to
recompile the kernel driver, which isn't an easy task for everyone.
So, I propose that we add a module parameter to all Super-I/O based
hardware monitoring drivers, letting advanced users force the driver
to load on their machine. The user has to provide the device ID of a
supposedly compatible device. This requires looking at the source code or
a datasheet, so I am confident that users can't randomly force a driver
without knowing what they are doing. Thus this should be relatively safe.
As you can see from the code, the implementation is pretty simple and
unintrusive.

As indirectly reported by Olof Johansson, the lm90 driver uses a
custom i2c read function even during detection, at which point we
don't know yet what device we're talking with. It would make more
sense to only use the generic i2c read function at this point, so
that we don't log irrelevant errors on misdetection.

The fan speeds reported by the gl518sm driver are twice as much as they
should. It's currently reporting the number of pulses per minute, not
rotations per minute, while typical fans emit two pulses per rotation.
This explains why all reports with this driver had very high speed
values (between 9000 to 12000 RPM). Odd that nobody ever actually
complained about this bug.

Point taken regarding the aacraid driver. Dropped the VALID bit, and
then did some cleanup/simplification of the set_sense procedure and
the associated parameters. Mike did some preliminary tests when the
VALID bit was dropped before the 'Re: [PATCH] [SCSI] sd: make error
handling more robust' patches came on the scene. The change in the
SCSI subsystem does make this enclosed aacraid patch unnecessary, so
this aacraid patch is merely post battle ground cleanup. If the
simplification is an issue, repugnant, too much for a back-port to the
stable trees or clouds the point, this patch could be happily
distilled down to:

This adds support to SCSI for enclosure services devices. It also makes
use of the enclosure services added in an earlier patch to display the
enclosure topology in sysfs.
At the moment, the enclosures are SAS specific, but if anyone actually
has a non-SAS enclosure that follows the SES-2 standard, we can add that
as well.
On my Vitesse based system, the enclosures show up like this:
sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/

You can flash the various blinky lights by echoing to the fault and locate files.
>From the device's point of view, you can see it has an enclosure like this:
sparkweed:~# ls /sys/class/scsi_disk/0\:0\:0\:0/device/
block:sda generic queue_depth state

driver modalias scsi_disk:0:0:0:0 vendor
enclosure_component:SLOT 001 model scsi_generic:sg0
evt_media_change power scsi_level
Note the enclosure_component:SLOT 001 which shows where in the enclosure
this device fits.
The astute will notice that I'm using SCSI VPD Inquiries to identify the
devices. This, unfortunately, won't work for SATA devices unless we do
some really nasty hacking about on the SAT because the only think that
knows the SAS addresses for SATA devices is libsas, not libata where the
SAT resides.

When sending a SCSI command to a tape drive via the SCSI Generic (sg)
driver, if the command has a data transfer length more than
scatter_elem_sz (32 KB default) and not a multiple of 512, then I either
hit BUG_ON(!valid_dma_direction(direction)) in dma_unmap_sg() or else
the command never completes (depending on the LLDD).
When constructing scatterlists, the sg driver rounds up the scatterlist
element sizes to be a multiple of 512. This can result in
sum(scatterlist lengths) > bufflen. In this case, scsi_req_map_sg()
incorrectly sets bio->bi_size to sum(scatterlist lengths) rather than to
bufflen. When the command completes, req_bio_endio() detects that
bio->bi_size != 0, and so it doesn't call bio_endio(). This causes the
command to be resubmitted, resulting in BUG_ON or the command never
completing.
This patch makes scsi_req_map_sg() set bio->bi_size to bufflen rather
than to sum(scatterlist lengths), which fixes the problem.
