Generally use NULL instead of explicitly casting 0 to some pointer type.

Flesh out BUF_CMD_FLUSH support.

Apply patch supplied in FreeBSD-PR to ata-raid code:

"A drive that was once part of an ataraid device, when added back to the
machine that it was on, shows up as a new ataraid device. This new ataraid
device tries to use all the drives that were originally in the RAID.
Results can range from a confusion to a real mess."

Remove bogus checks after kmalloc(M_WAITOK) which never returns NULL.

we do not want to shift by the block size, which is much larger than
the number of bits held in bio_offset.

Continue untangling the disklabel. Have most disk device drivers fill out
and install a generic disk_info structure instead of filling out random
fields in the disklabel.

The generic disk_info structure uses a 64 bit integer to represent
the media size in bytes or total sector count.

Misc cleanups for NATA ataraid, and write ata_raid_dump() to look like
something that will actually work. I did not take the same approach as with
ad_dump() here, because that takes just too much code duplication between
ata_raid_strategy() and ata_raid_dump().

Initial import of the port of the new(er) FreeBSD ATA code.

Note this code has not yet been hooked into the build as such, unless you (unwisely) specify the devices in your kernel config according to sys/conf/files. The modules are also excluded from the module build due to not having a SUBDIR entry in sys/dev/disk/Makefile. The PCI code isn't yet operation pending a patch for sys/bus/pci/pci.c I will send to kernel@ shortly. It short-circuits lazy resource allocation for PCI ATA controllers in legacy mode (i.e. on legacy ISA ATA addresses, which are not configured in the PCI BARs).

The userland utility used to control nata ('natacontrol') and documentation will follow later. Also, be aware only nata, natapci, natadisk and natapicd have seen testing on real hardware so far. nataraid, natausb and natacam are probably not compilable yet, I need to clean those up.
