201408,201325,200089,198822,197373,197372,197214,196162). Since one of those changes was a semicolon cleanup from somebody else, this touches a lot more.

MFC revision 199069:

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. This instant MFC was requested by re@ (kensmith) in preparation for 8.0-RC3. Reported by: Jirka Mikulas Submitted by: Erich Chen (Areca)

We no longer need to use d_thread_t, migrate to struct thread *.

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.

fix arcmsr_attach, probe, detach, and shutdown prototypes to match newbus.

Replace all calls to minor() with dev2unit().

2008-09-27T08:51:18Z

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. Reviewed by: kib
