 1.16  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.15  24-Apr-2021  thorpej branches: 1.15.8;
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?).

KNF. No functional change.
 1.13  27-Oct-2012  chs branches: 1.13.14;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.12  12-Sep-2009  tsutsui branches: 1.12.12; 1.12.22;
Make compile with options DEBUG.
 1.11  12-May-2009  cegger struct device * -> device_t, no functional changes intended.
 1.10  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.9  28-Apr-2008  martin branches: 1.9.14;
Remove clause 3 and 4 from TNF licenses
 1.8  08-Apr-2008  cegger branches: 1.8.2; 1.8.4;
use aprint_*_dev and device_xname
 1.7  19-Oct-2007  ad branches: 1.7.16;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.6  09-Jul-2007  ad branches: 1.6.6; 1.6.8; 1.6.12;
Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements
 1.5  10-Jan-2007  cube branches: 1.5.6; 1.5.8;
Complete initialiser.
 1.4  11-Dec-2005  christos branches: 1.4.20;
merge ktrace-lwp.
 1.3  27-Feb-2005  perry branches: 1.3.4;
nuke trailing whitespace
 1.2  14-Sep-2004  drochner branches: 1.2.4; 1.2.6;
Separate the namespace for default (ie unspecified) locators used
by the isa.c bus driver and the "address/whatever not specified"
argument passed to leaf device drivers.
The former is "ISACF_XXX_DEFAULT" as generaterd by config(8), the latter
"ISA_UNKNOWN_XXX", defined in isavar.h.
This way we save a dependency of every ISA device driver on "locators.h".
 1.1  02-Jun-2003  gmcgarry branches: 1.1.2;

including boards made by Captial Equipment Corp.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

 1.14.34.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.15.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
