Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

branches: 1.10.2;
Add support for dynamic rescan of cache service logical drives, using
the ioctl issued by the ICP RAID management libraries (used by the
storcon and iirconfig tools). This requires some infrastructure changes:
* Add a "service callback" mechanism that the ld driver (cache service)
and the iopsp driver (raw service) can register with the icp parent.
Right now this callback allows the children to adjust their notion of
how many command openings are available.
* Add a mutex around the icp ioctl handler, allowing only one thread
to execute an ioctl at a time.
* Add a way to freeze the controller command queue. We stop all I/O
while processing rescans (due to the semantics of icp_cmd()).
* Make icp_cmd() work when !cold.
* Add detach support to ld@icp.

Another fix from Achim Leubner @ ICP:

Test-busy *before* marking the controller as processing a user ioctl,
otherwise the command queue could stall permanently if test-busy returned
true.

Add support for the user-generated command interface and event logging
required by the ICP-Vortex management tools. Many thanks to Achim Leubner

- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().

- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups

branches: 1.1.2;
Add a driver for ICP-Vortex GDT and Intel Storage RAID controllers. Parts
taken from OpenBSD. Test hardware kindly provided by Intel. This still needs
management bits, and doesn't support older controllers, but that shouldn't
be hard to fix.

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

s/initalize/initialize/ in comment or printf message.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

branches: 1.30.8; 1.30.18;
Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.

branches: 1.29.22;
Make various bits of debug code compile again.

Remove clause 3 and 4 from TNF licenses

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

branches: 1.24.2;
Remove a use of lockmgr/LOCK_INITIALIZER.

branches: 1.23.2;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

__unused removal on arguments; approved by core.

- sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386

merge FreeBSD timecounters from branch simonb-timecounters
- struct timeval time is gone
time.tv_sec -> time_second
- struct timeval mono_time is gone
mono_time.tv_sec -> time_uptime
- access to time via
{get,}{micro,nano,bin}time()
get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)
- further reading:

Make almost everything #include <sys/bswap.h> instead of <machine/bswap.h>
The bswap.h and endian.h files are all rather incestuous, but I want to
get the constant folding stuff into one place - sys/bswap.h

merge ktrace-lwp.

kill a number of autoconf submatch functions which follow the
standard scheme:
if (<configured> != <wildcard> && <configured> != <real>)
then fail
else
ask device match function

This is handled by config_stdsubmatch() now.

replace the "locdesc_t" structure carrying the number of locators
explicitely by a plain integer array
the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks

branches: 1.14.4;
nuke trailing whitespace

branches: 1.13.4; 1.13.6;
a round of autoconf cleanup:
-convert submatch() style functions (passed to config_search() or
config_found_sm()) to the locator passing variants
-pass interface attributes in some cases
-make submatch() functions look uniformly as far as possible
-avoid macros which just hide cfdata members, and reduce dependencies
on "locators.h"

Remove bogus initializer, and fix a typo in a loop variable instead.

Fix uninitialized variable warnings

branches: 1.10.2;
Add support for dynamic rescan of cache service logical drives, using
the ioctl issued by the ICP RAID management libraries (used by the
storcon and iirconfig tools). This requires some infrastructure changes:
* Add a "service callback" mechanism that the ld driver (cache service)
and the iopsp driver (raw service) can register with the icp parent.
Right now this callback allows the children to adjust their notion of
how many command openings are available.
* Add a mutex around the icp ioctl handler, allowing only one thread
to execute an ioctl at a time.
* Add a way to freeze the controller command queue. We stop all I/O
while processing rescans (due to the semantics of icp_cmd()).
* Make icp_cmd() work when !cold.
* Add detach support to ld@icp.

Another fix from Achim Leubner @ ICP:

Test-busy *before* marking the controller as processing a user ioctl,
otherwise the command queue could stall permanently if test-busy returned
true.

Add support for the user-generated command interface and event logging
required by the ICP-Vortex management tools. Many thanks to Achim Leubner
at ICP-Vortex for a few bug fixes and for testing.

Use aprint_*().

Use aprint_normal() in cfprint routines.

In icp_init(), initialise the "state" variable before incrementing it.

remove trailing \n in panic(). approved perry.

Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.
