dd0b4fb6d5 Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c.  It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code.  The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync().  Previously this was done in a type specific
way.  Now it is done in a generic way by recording the list of
virtuals in the map.

b79dc8a8da Fix an issue that caused the kernel to panic inside CTL when trying
to attach to target capable HBAs that implement the old immediate
notify (XPT_IMMED_NOTIFY) and notify acknowledge (XPT_NOTIFY_ACK)
CCBs.  The new API has been in place since SVN change 196008 in
2009.

The solution is two-fold:  fix CTL to handle the responses from the
HBAs, and convert the HBA drivers in question to use the new API.

These drivers have not been tested with CTL, so how well they will
interoperate with CTL is unknown.

scsi_target.c:	Update the userland target example code to use the
		new immediate notify API.

scsi_ctl.c:	Detect when an immediate notify CCB is returned
		with CAM_REQ_INVALID or CAM_PROVIDE_FAIL status,
		and just free it.

		Fix a duplicate assignment.

aic79xx.c,
aic79xx_osm.c:	Update the aic79xx driver to use the new API.
		Target mode is not enabled on for this driver, so
		the changes will have no practical effect.

aic7xxx.c,
aic7xxx_osm.c:	Update the aic7xxx driver to use the new API.

sbp_targ.c:	Update the firewire target code to work with the
		new API.

mpt_cam.c:	Update the mpt(4) driver to work with the new API.
		Target mode is only enabled for Fibre Channel
		mpt(4) devices.

56e4bfe54d Fix build of aicasm when CC=clang. This was due to a side-effect of the
EARLY_BUILD macro: the -Qunused-arguments flag isn't passed anymore when
building this particular program.  However, with clang 3.1 and -Werror,
such unused argument warnings are flagged as errors, causing buildkernel
to fail at this stage, due to the -nostdinc flag passed during linking.
Since the -nostdinc flag isn't actually needed, just remove it.

187278cadc For every instance of '.if ${CC} == "foo"' or '.if ${CC} != "foo"' in
Makefiles or *.mk files, use ${CC:T:Mfoo} instead, so only the basename
of the compiler command (excluding any arguments) is considered.

This allows you to use, for example, CC="/nondefault/path/clang -xxx",
and still have the various tests in bsd.*.mk identify your compiler as
clang correctly.

ICC if cases were also changed.

b744190698 Correct logic bug in aicasm's undefined register bit access detection code.
The code in question verifies that all register write operations only change
bits that are defined (in the register definition file) for that effected
register.  The bug effectively disabled this checking.

o Fix the check by testing the opcode against all supported read ("and" based)
  operands.

o Add missing bit definitions to the aic7xxx and aic79xx register definition
  files so that the warning (treated as a fatal error) does not spuriously
  fire.

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.

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.
