 1.11  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.10  24-Apr-2021  thorpej branches: 1.10.8;
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?).
 1.9  20-Nov-2020  thorpej branches: 1.9.2;
malloc(9) -> kmem(9)
 1.8  10-Nov-2019  chs branches: 1.8.8;
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.
 1.7  30-Aug-2019  riastradh Don't dereference pointer when we're about to panic because it's null.

Reported by Dr Silvio Cesare of InfoSect.
 1.6  27-Oct-2012  chs branches: 1.6.38;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.5  25-Nov-2009  rmind branches: 1.5.12; 1.5.22;
Remove IPL_LPT and IPL_IPI aliases, use the actual IPLs.
Fix some broken comments.
 1.4  06-Dec-2008  cliff branches: 1.4.4; 1.4.6; 1.4.10;
add gemini pseudo-nic and support code.
 1.3  26-Nov-2008  matt gpn, not gnp.
 1.2  26-Nov-2008  matt Add children of geminiipi
 1.1  20-Nov-2008  cliff add driver for low level inter-processor-interrupt
provides functions for establish/disestablish IPI ISR,
and function to signal IPI to the other CPU.
 1.4.10.3  11-Mar-2010  yamt sync with head
 1.4.10.2  04-May-2009  yamt sync with head.
 1.4.10.1  06-Dec-2008  yamt file gemini_ipi.c was added on branch yamt-nfs-mp on 2009-05-04 08:10:41 +0000
 1.4.6.2  19-Jan-2009  skrll Sync with HEAD.
 1.4.6.1  06-Dec-2008  skrll file gemini_ipi.c was added on branch nick-hppapmap on 2009-01-19 13:15:58 +0000
 1.4.4.2  17-Jan-2009  mjf Sync with HEAD.
 1.4.4.1  06-Dec-2008  mjf file gemini_ipi.c was added on branch mjf-devfs2 on 2009-01-17 13:27:52 +0000
 1.5.22.1  20-Nov-2012  tls Resync to 2012-11-19 00:00:00 UTC
 1.5.12.1  30-Oct-2012  yamt sync with head
 1.6.38.1  13-Apr-2020  martin Mostly merge changes from HEAD upto 20200411
 1.8.8.1  14-Dec-2020  thorpej Sync w/ HEAD.
 1.9.2.1  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.
 1.10.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
