 1.20  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.19  24-Apr-2021  thorpej branches: 1.19.8;
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?).
 1.18  25-Jul-2014  dholland branches: 1.18.42;
Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.17  16-Mar-2014  dholland branches: 1.17.2;
Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
 1.16  12-Nov-2012  skrll branches: 1.16.2;
C99 types
 1.15  27-Oct-2012  chs split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.14  01-Jul-2011  dyoung branches: 1.14.2; 1.14.12;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.13  14-Mar-2009  dsl ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
 1.12  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.11  11-Jun-2008  cegger branches: 1.11.4; 1.11.10;
use device_lookup_private to get softc
 1.10  28-Apr-2008  martin branches: 1.10.2; 1.10.4;
Remove clause 3 and 4 from TNF licenses
 1.9  04-Mar-2007  christos branches: 1.9.40; 1.9.42; 1.9.44;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.8  24-Jan-2007  hubertf branches: 1.8.2;
Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.
 1.7  31-Aug-2006  matt branches: 1.7.2;
Make these compile again. (#include <arm/ep93xx/epgpioreg.h> and
do the proc -> lwp changeover).

 1.2  09-Jan-2005  joff o reversed sense of RS in writereg

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
 1.14.2.2  16-Jan-2013  yamt sync with (a bit old) head
 1.14.2.1  30-Oct-2012  yamt sync with head

 1.18.42.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as

to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.19.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
