peter fuerst a5d8421b2f [SCSI] wd33c93: Fast SCSI with WD33C93B
Attached are patches, which help to utilize more of the WD33C93B SCSI
controller's capabilities.

1) Added/changed all the necessary code to enable Burst Mode DMA. Only
   Single Byte DMA was used before.

2) Added/changed all the necessary code to enable Fast-10 SCSI transfers.

3) The original driver inadvertently used a transfer period of 1000-800ns
   (the lowest possible transfer rate) for asynchronous data transfers,
   instead of the (configurable) default period intended for this purpose,
   if the target responded to a SDTR not with a Reject-message, but with
   a zero-SDTR. This issue was fixed.
   Moreover, in case of a Reject the driver used the default-period's
   initialization-value instead of its (maybe smaller) current value. The
   missing assignment was added.

4) The driver's commandline- and proc-file-interface was augmented to
   handle the new options properly.

The WD33C93 manual, found at
http://www.datasheet.in/datasheet-html/W/D/3/WD33C93B_WesternDigital.pdf.html,
was very helpful.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
