b40ce4165d KSE Milestone 2 
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

a2dca80a1d Provide the interface to atacontrol and associated logic. 
see atacontrol(8) for more.

Also the ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC and ATA_ENABLE_TAGS
options are gone, use the tuneables listed in ata.4 instead from
the loader (this makes it possible to switch off DMA before the
driver has to touch the devices on broken hardware).

b17f7a1aa5 Introduce busspace instead of the good old in/out instructions. 
Not pretty but it works (I hope)...

0cdc179319 Only offset raid disks > 1 on the HPT, this should solve the 
boot problems..
However this demands that dangerously dedicated disks use an
offset of at least 10 from the start to not overwrite the
raid config sector on the HPT...

be swapped around and still be put in the correct order in a raid.

Use by defining the RAID in the BIOS and the "ar driver will pick it up
automagically...
