 1.45  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.44  24-Apr-2021  thorpej branches: 1.44.8;
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?).
 1.43  10-Nov-2019  chs branches: 1.43.10;
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.

 1.41  13-Nov-2010  uebayasi branches: 1.41.2;

 1.30  11-Dec-2005  christos merge ktrace-lwp.
 1.29  30-May-2005  christos branches: 1.29.2;
- add missing const
- fix variable shadowing
- remove unneeded casts
 1.28  21-Feb-2005  thorpej Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name
everything "scsi_*", since we really are talking about the SCSI command
set, ATAPI transport not withstanding. Improve the names of many structures,
and prepend "SCSI_" onto all SCSI command opcodes. Place items described
by the SCSI Primary Commands document into scsi_spc.h.
 1.27  02-Jan-2005  tsutsui branches: 1.27.2; 1.27.4;
u_intNN_t -> uintNN_t
 1.26  07-Dec-2004  thorpej When checking the CDB length, check against the field in the SCB
that we're actually storing it to.

XXX Should be re-examined; this is not actually a hardware-constrained
size with this driver.
 1.25  25-Sep-2004  tsutsui Use ANSI function decls.
 1.24  02-Nov-2003  wiz branches: 1.24.4;

 1.22  03-May-2003  wiz branches: 1.22.2;
DMA, not dma nor Dma.
 1.21  20-Jan-2003  simonb The Double-Semi-Colon Police.
 1.20  08-Dec-2002  jmc Put back MSG_IDENTIFY_LUNMASK (renamed to just be within the IHA namespace.
The definitions were not the same between the scsi_messages file and this
definition so simply removing it here and letting the other one be used
results in incorrect behavior (regardless of whether it made the code
compile....)
 1.19  14-Nov-2002  tsutsui Sync with copyright verbiage update of OpenBSD's iha(4).
 1.18  27-Sep-2002  provos remove trailing \n in panic(). approved perry.
 1.17  05-Apr-2002  bouyer Implement mstohz() as discussed on tech-kern, and use it in SCSI drivers
to convert xs->timeout to callout() parameter.
 1.16  15-Mar-2002  tsutsui Remove an arg name in prototype declaration.
 1.15  09-Feb-2002  tsutsui - rename struct iha_scsi_req_q -> struct iha_scb
- reorder some functions
- some more cosmetics
 1.14  16-Dec-2001  tsutsui malloc() + memset() -> malloc() with M_ZERO flag
 1.13  18-Nov-2001  tsutsui - Use MI ADAPTER_REQ_SET_XFER_MODE callback.
- Nuke some magic numbers.
 1.12  17-Nov-2001  tsutsui - make sure to call bus_dmamap_unload() even after request sense
- fix usage of scb flags
- misc cleanup
 1.11  13-Nov-2001  lukem add/cleanup RCSID
 1.10  29-Sep-2001  tsutsui Calculate offsets of sglist dinamically rather than use an static array
because PAGE_SIZE is not constant on some ports.
 1.9  27-Sep-2001  tsutsui Remove iha_minphys() and use minphys() instead.
 1.8  27-Jul-2001  tsutsui branches: 1.8.2;
Fix some comments and remove an unused define. Partially from OpenBSD.
 1.7  27-Jul-2001  tsutsui Pull up some changes from OpenBSD's iha.c rev 1.6:
- rename tul_* functions/variables iha_* for consistency
- disable updating EEPROM routine, which does not work anyway
- make iha_rate_tbl[] const
 1.6  27-Jul-2001  tsutsui Pull up some changes from OpenBSD's iha.c rev 1.5:
- minor code cleanups
- rename some functions for better consistensy/clarity

- a couple of minor code clarifications to eliminate extra return
statements and make absolutely sure actscb is NULL during a reselect

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.
