This is what enables large commands. If we need to allocate an
sgtable that doesn't fit in a single page, allocate several
SCSI_MAX_SG_SEGMENTS sized tables and chain them together.
SCSI defaults to large chained sg tables, if the arch supports it.

Expose this setting for now, so that users can play with enabling
large commands without defaulting it to on globally. This is a debug
patch, it will be dropped for the final versions.

Hi,
A repost of this patchset, which adds support forchaining of sg tables.
This enables much larger IO commands, since we don't have to allocate
large consecutive pieces of memory to represent the sgtable of a
huge command. Right now Linux is limited to somewhere between 128 and 256
segments,

We don't need to do more on x86, there's no iommu to be worried about.

The dma mapping helpers need to be converted to using
sg helpers as well, so they will work with a chained
sglist setup.

The core of the patch - allow the last sg element in a scatterlist
table to point to the start of a new table. We overload the LSB of
the page pointer to indicate whether this is a valid sg entry, or
merely a link to the next list.

This is a trivial patch, I will merge to my blackfin-git tree.
