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!

[SCSI] implement parameter limits in the SPI transport class There's a basic need not to have parameters go under or over certain values when doing domain validation. The basic ones are max_offset, max_width and min_period This patch makes the transport class take and enforce these three limits. Currently they can be set by the user, although they could obviously be read from the HBA's on-board NVRAM area during slave_configure (if it has one).

[SCSI] add missing hold_mcs parameter to the spi transport class This parameter is important only to people who take the time to tune the margin control settings, otherwise it's completely irrelevant. However, just in case anyone should want to do this, it's appropriate to include the parameter. I don't do anything with it in DV by design, so the parameter will come up as off by default, so if anyone actually wants to play with the margin control settings they'll have to enable it under the spi_transport class first.

scsi: remove abuses of scsi_populate_tag Unless we want to build a SPI tag message we should just check SCMD_TAGGED instead of reverse engineering a tag type through the use of scsi_populate_tag_msg. Also rename the function to spi_populate_tag_msg, make it behave like the other spi message helpers, and move it to the spi transport class.

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!
