03bc68ca09 Disable K&R style function definitions for WARNS=6.
Unfortunately there are two slight problems with that:

- Yacc and lex might generate code that generates warnings because of
  this. Require yacc and lex to be rebuilt during bootstrap. I'm not
  incrementing __FreeBSD_version here, because I assume someone else
  will do this eventually.

- When running `make buildkernel', it uses share/mk from the source
  treeo to build aicasm. Because aicasm also depends on lex, this would
  break. Lower WARNS to 5 for now. We should just increment it to 6
  again somewhere in the very far future.

52c9ce25d8 Separate the parallel scsi knowledge out of the core of the XPT, and
modularize it so that new transports can be created.

Add a transport for SATA

Add a periph+protocol layer for ATA

Add a driver for AHCI-compliant hardware.

Add a maxio field to CAM so that drivers can advertise their max
I/O capability.  Modify various drivers so that they are insulated
from the value of MAXPHYS.

The new ATA/SATA code supports AHCI-compliant hardware, and will override
the classic ATA driver if it is loaded as a module at boot time or compiled
into the kernel.  The stack now support NCQ (tagged queueing) for increased
performance on modern SATA drives.  It also supports port multipliers.

ATA drives are accessed via 'ada' device nodes.  ATAPI drives are
accessed via 'cd' device nodes.  They can all be enumerated and manipulated
via camcontrol, just like SCSI drives.  SCSI commands are not translated to
their ATA equivalents; ATA native commands are used throughout the entire
stack, including camcontrol.  See the camcontrol manpage for further
details.  Testing this code may require that you update your fstab, and
possibly modify your BIOS to enable AHCI functionality, if available.

This code is very experimental at the moment.  The userland ABI/API has
changed, so applications will need to be recompiled.  It may change
further in the near future.  The 'ada' device name may also change as
more infrastructure is completed in this project.  The goal is to
eventually put all CAM busses and devices until newbus, allowing for
interesting topology and management options.

Few functional changes will be seen with existing SCSI/SAS/FC drivers,
though the userland ABI has still changed.  In the future, transports
specific modules for SAS and FC may appear in order to better support
the topologies and capabilities of these technologies.

The modularization of CAM and the addition of the ATA/SATA modules is
meant to break CAM out of the mold of being specific to SCSI, letting it
grow to be a framework for arbitrary transports and protocols.  It also
allows drivers to be written to support discrete hardware without
jeopardizing the stability of non-related hardware.  While only an AHCI
driver is provided now, a Silicon Image driver is also in the works.
Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware
is possible and encouraged.  Help with new transports is also encouraged.

3745c395ec Rename the kthread_xxx (e.g. kthread_create()) calls
to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.

I'd LOVE to do this rename in 7.0  so that we can eventually MFC the
new kthread_xxx() calls.

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.

7628acd8ee Up until now, the free SCB pool received only a small initial allocation,
and new SCBs were allocated on demand later if needed.  This has two
problems.  First, allocating SCBs involves allocating contiguous memory,
and if memory is exhausted then the VM will try to page out to satisfy
the request, leading to recursion and deadlock.  The second problem is
that it can cause lock order reversals due to parts of the VM still being
under Giant.

Fix the problem be allocating the full pool at driver attach, when it is
safe to do so.

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.

378f231e7d add a newbus method for obtaining the bus's bus_dma_tag_t... This is
required by arches like sparc64 (not yet implemented) and sun4v where there
are seperate IOMMU's for each PCI bus...  For all other arches, it will
end up returning NULL, which makes it a no-op...

Convert a few drivers (the ones we've been working w/ on sun4v) to the
new convection...  Eventually all drivers will need to replace the parent
tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for
each driver, and will require hand inspection...

e1e31c0e43 Clean up the way we handle auxiliary commands for a given ddb command
table.  Previously, the ddb code knew of each linker set of auxiliary
commands and which explicit command list they were tied to.  These changes
add a simple command_table struct that contains both the static list of
commands and the pointers for any auxiliary linker set of additional
commands.  This also makes it possible for other arbitrary command tables
to be defined in other parts of the kernel w/o having to edit ddb itself.

The DB_SET macro has also been trimmed down to just creating an entry in
a linker set.  A new DB_FUNC macro does what the old DB_SET did which is
to not only add an entry to the linker set but also to include a function
prototype for the function being added.  With these changes, it's now also
possible to create aliases for ddb functions using DB_SET() directly if
desired.

05899a48a7 On Rev. B silicon, we disabled the enhanced busfree detection logic to
close holes in detecting busfrees that occur after a packetized target
transitions to a non-packetized phase.  The most common case where this
occurs is when a target is externally reset so the controller believes
a packetzied negotiation agreement is still in effect.  Unfortunately,
disabling this feature seems to cause problems for the 7901B.  Re-enable
ehanced busfree detection for this part until I can get my hands on a
samble to figure out if the old workaround is necessary and, if so, how
to make it work correctly.
