2d7994d97e Get rid of all the "long long"/"maxint" casting around in printf's.
On all our platforms intmax == int64_t so simply using %j to print
int64_t's is safe all over, and doesn't pullute the code.

5bb84bc84b Normalize a significant number of kernel malloc type names:
- Prefer '_' to ' ', as it results in more easily parsed results in
  memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
  as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
  memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
  attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion.  Similar changes are required for UMA zone names.

8ca4df3299 This is the much rumoured ATA mkIII update that I've been working on.
o       ATA is now fully newbus'd and split into modules.
        This means that on a modern system you just load "atapci and ata"
        to get the base support, and then one or more of the device
        subdrivers "atadisk atapicd atapifd atapist ataraid".
        All can be loaded/unloaded anytime, but for obvious reasons you
        dont want to unload atadisk when you have mounted filesystems.

o       The device identify part of the probe has been rewritten to fix
        the problems with odd devices the old had, and to try to remove
        so of the long delays some HW could provoke. Also probing is done
	without the need for interrupts, making earlier probing possible.

o       SATA devices can be hot inserted/removed and devices will be created/
        removed in /dev accordingly.
	NOTE: only supported on controllers that has this feature:
	Promise and Silicon Image for now.
	On other controllers the usual atacontrol detach/attach dance is
	still needed.

o	Support for "atomic" composite ATA requests used for RAID.

o       ATA RAID support has been rewritten and and now supports these
        metadata formats:
                 "Adaptec HostRAID"
                 "Highpoint V2 RocketRAID"
                 "Highpoint V3 RocketRAID"
                 "Intel MatrixRAID"
                 "Integrated Technology Express"
                 "LSILogic V2 MegaRAID"
                 "LSILogic V3 MegaRAID"
                 "Promise FastTrak"
                 "Silicon Image Medley"
		 "FreeBSD PseudoRAID"

o       Update the ioctl API to match new RAID levels etc.

o       Update atacontrol to know about the new RAID levels etc
        NOTE: you need to recompile atacontrol with the new sys/ata.h,
        make world will take care of that.
	NOTE2: that rebuild is done differently from the old system as
	the rebuild is now done piggybacked on read requests to the
	array, so atacontrol simply starts a background "dd" to rebuild
	the array.

o       The reinit code has been worked over to be much more robust.

o       The timeout code has been overhauled for races.

o	Support of new chipsets.

o       Lots of fixes for bugs found while doing the modulerization and
        reviewing the old code.

Missing or changed features from current ATA:

o       atapi-cd no longer has support for ATAPI changers. Todays its
        much cheaper and alot faster to copy those CD images to disk
        and serve them from there. Besides they dont seem to be made
        anymore, maybe for that exact reason.

o       ATA RAID can only read metadata from all the above metadata formats,
	not write all of them (Promise and Highpoint V2 so far). This means
	that arrays can be picked up from the BIOS, but they cannot be
	created from FreeBSD. There is more to it than just the missing
	write metadata support, those formats are not unique to a given
	controller like Promise and Highpoint formats, instead they exist
	for several types, and even worse, some controllers can have
	different formats and its impossible to tell which one.
	The outcome is that we cannot reliably create the metadata of those
	formats and be sure the controller BIOS will understand it.
	However write support is needed to update/fail/rebuild the arrays
	properly so it sits fairly high on the TODO list.

o       So far atapicam is not supported with these changes. When/if this
	will change is up to the maintainer of atapi-cam so go there for
	questions.

b5dee91f5f Remove the old ATA_*LOCK_CH macros that used atomic ops and use
mutexes instead.
This closes the last (known) race issues in ATA which should fix
the various hangs etc seen on heavy loaded systems.

Change from using timeout functions to using callout functions in
the timeout code. This together with above closes the race that could
happen if timeout and device interrupt occured simultaniously.

Also fix the possible recursion in ata_reinit() on very dodgy
devices that could take us down in the probe.

a49513587b Ignore leading '_' in model name returned by devices.
This make "_NEC" devices appear as "NEC" which is more corrent.
The reason is tha NEC originally screwed up on the byteorder in the

so that not every ATA driver on the planet would call them "EN C" :)

f2972d7eb8 Add support for the Promise command sequencer present on all modern Promise
controllers (PDC203** PDC206**).

This also adds preliminary support for the Promise SX4/SX4000 but *only*
as a "normal" Promise ATA controller (ATA RAID's are supported though
but only RAID0, RAID1 and RAID0+1).

This cuts off yet another 5-8% of the command overhead on promise controllers,
making them the fastest we have ever had support for.

Work is now continuing to add support for this in ATA RAID, to accellerate
ATA RAID quite a bit on these controllers, and especially the SX4/SX4000
series as they have quite a few tricks in there..

This commit also adds a few fixes to the SATA code needed for proper support.

a7a120f649 Overhaul of the timeout/reinit framework. This should clear up most
of the leftovers from the old version that really doesn't work anymore.

Add a reset function for host-end of the ATA channel. This is needed
for the SiI3112 in order to whack it back to reality if a device
locks up the SATA interface (thereby preventing that we can reset the
device). The result is that ATA now recovers from the timeouts that
happens with the SiI3112A and more or less all disks based on old
PATA electronics with a Marvell PATA->SATA converter. This includes
lots of the popular SATA dongles and the WDC Raptor disks..

5fdbb0d222 This is a major rework of the ATA driver (ATAng)
Restructure the way ATA/ATAPI commands are processed, use a common
ata_request structure for both. This centralises the way requests
are handled so locking is much easier to handle.

The driver is now layered much more cleanly to seperate the lowlevel
HW access so it can be tailored to specific controllers without touching
the upper layers. This is needed to support some of the newer
semi-intelligent ATA controllers showing up.

The top level drivers (disk, ATAPI devices) are more or less still
the same with just corrections to use the new interface.

Pull ATA out from under Gaint now that locking can be done in a sane way.

Add support for a the National Geode SC1100. Thanks to Soekris engineering
for sponsoring a Soekris 4801 to make this support.

Fixed alot of small bugs in the chipset code for various chips now
we are around in that corner anyways.

This completes the ATA RAID support, since all functions to manipulate

are only nessesary for booting.

I decided to allow for creation of ATA RAID's on any ATA controller, but
please keep in mind the restrictions on that. Due to the BIOS not
knowing what to do you can only boot from a RAID1 or the first disk
in a SPAN, if its not located on a "real" ATA RAID controller like
the Promise or Highpoint controllers.

6f87be981b Major update of the ATA RAID code, part 3:
Add code to properly detach/attach disks that are part of a RAID.

Mark a disk that is attached on an ATA channel belonging to a
RAID as a spare disk that can be used for rebuilding failed RAID1's.

Add support for rebuilding failed RAID1's.

Several fixes to the detach/attach code.

For replacing a disk in a failed RAID1 do the following:

Find the controller channel# of the failed disk.

Exec 'atacontrol detach <channel#>' to free the disk from the system.

Replace the failed disk with a new one of at least the same size.
If your have your disks in drawers/enclosures this can be done with
the system still running.

Exec 'atacontrol attach <channel#>' to add the disk to the system and
mark it as a valid spare for rebuild.

Exec 'atacontrol rebuild <array#>'

The system will rebuild the array on the fly, the array can still
be used during this, although with slower performance.

Please let me know of any problems with this!

6ddce9039b Major update of the ATA RAID code, part 1:
Overhaul of the attach/detach code and structures, there were some nasty
bugs in the old implementation. This made it possible to collapse the
ATA/ATAPI device control structures into one generic structure.

A note here, the kernel is NOT ready for detach of active devices,
it fails all over in random places, but for inactive devices it works.
However for ATA RAID this works, since the RAID abstration layer
insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the
physical disks.

Proberly detect the RAID's from the BIOS, and mark critical RAID1
arrays as such, but continue if there is enough of the mirror left
to do so.

Properly fail arrays on a live system. For RAID0 that means return EIO,
and for RAID1 it means continue on the still working part of the mirror
if possible, else return EIO.
If the state changes, log this to the console.

Allow for Promise & Highpoint controllers/arrays to coexist on the
same machine. It is not possible to distribute arrays over different
makes of controllers though.

If Promise SuperSwap enclosures are used, signal disk state on the
status LED on the front.

Misc fixes that I had lying around for various minor bugs.
