d74001ad8d Apply vendor version 1.20.00.17.
This version adds support for ARC1880; additionally this version fixed
an issue where all devices on a SAS port gets offlined when any device
failed on the port [1].

Many thanks to Areca for continuing to support FreeBSD.

641182ba04 Initialize the whole message unit's DMA buffer to zero, this fixes a panic
during boot when ARC1200 is being used with certain motherboard models.

This commit brings the driver to the same state of vendor's 1.20.00.16
release.  Many thanks to Areca for their continued support to FreeBSD.

9d98ff4d69 Tell CAM that SPI disconnect works, which in turn will let it use tags.
This fixes the low "max device openings" count that has lead to poor
performance in FreeBSD 7.0 and 7.1.

Extra thanks goes to Mike Tancsa at Sentex for providing a debug system for
this.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

5878cbeccf Make the driver fully MPSAFE. This fixes some serious locking problems
that could cause panics and corruption under moderate load.  Many thanks

their help in identifying and testing this.

b50569b71d Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

dc3a205bc4 Better fix for the errors under high load. Returning CAM_SCSI_BUSY is almost
never correct as CAM has no real understanding of it, and will just immediately
retry the command.  This leads to undesirable cycling of the camisr as well as
a high possibility for the command to exhaust its retries before the driver
can get around to servicing it.

The better fix, as demonstrated here, is to freeze the simq and mark the
command as needing to be tried.  Then when driver can service the command,
the simq gets unfrozen.  This is correct, and documented here to help reduce
the mystery.  However, it also points out a shortcoming in CAM error handling
that makes writing drivers harder.

bd3fd815a7 2nd and final commit that moves us to CAM_NEW_TRAN_CODE
as the default.

fa9ed86506 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.
