 1.46  20-Jul-2022  thorpej No need to test for __alpha__ || alpha ... just one will suffice.
 1.45  28-May-2022  andvar fix various typos, mainly in comments.
 1.44  11-Sep-2021  andvar Add missing double p and d for stopped and overriden accordingly.
Fix few more typos along the way, mainly in copy-pasted comments.
 1.43  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.42  24-Apr-2021  thorpej branches: 1.42.8;
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?).
 1.41  10-Nov-2019  chs branches: 1.41.10;
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.
 1.40  12-May-2009  cegger branches: 1.40.64;
struct cfdata * -> cfdata_t, no functional changes intended.
 1.39  18-Apr-2009  tsutsui Remove extra whitespace added by a stupid tool.

 1.36  29-Mar-2008  tsutsui branches: 1.36.2; 1.36.4;
Split softc and device_t for zsc(4) and its children.

XXX we should restructure MI APIs and make it really machine independent.
 1.35  09-Nov-2007  ad branches: 1.35.14;

 1.32  10-May-2006  skrll branches: 1.32.18; 1.32.32; 1.32.34; 1.32.36;
Fix a bunch of cast lvalues.
 1.31  31-Mar-2006  thorpej Use ANSI function decls, apply static.
 1.30  30-Mar-2006  thorpej Use device_private().
 1.29  11-Dec-2005  christos branches: 1.29.4; 1.29.6; 1.29.8; 1.29.10; 1.29.12;
merge ktrace-lwp.
 1.28  26-Aug-2005  drochner s/locdesc_t/int/g
 1.27  25-Aug-2005  drochner 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
 1.26  02-Jun-2005  drochner branches: 1.26.2;
avoid "volatile" cast-aways
 1.25  27-Feb-2005  perry nuke trailing whitespace
 1.24  04-Feb-2005  perry de-__P
 1.23  13-Sep-2004  drochner branches: 1.23.4; 1.23.6;
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"
 1.22  26-Aug-2004  drochner kick out the ioasic offset check which happens in submatch() now
 1.21  06-Mar-2003  matt branches: 1.21.2;
Add cn_halt and cn_flush entries to consdevs. (needed for dma-only console
devices).
 1.20  01-Jan-2003  thorpej Use aprint_normal() in cfprint routines.
 1.19  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.18  01-Oct-2002  thorpej Use CFATTACH_DECL().
 1.17  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.16  27-Sep-2002  thorpej 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.
 1.15  27-Sep-2002  thorpej Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.
 1.14  26-Sep-2002  thorpej G/c extern reference to ioasic_cd.
 1.13  26-Sep-2002  thorpej No need to make sure parent's cfdriver == &ioasic_cd.
 1.12  24-Sep-2002  ad Deal with the strange SCC wiring on TC IOASIC machines. Thanks to Bill
Studenmund and Jonathan Stone for useful comments.
 1.11  06-Sep-2002  gehenna Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
 1.10  12-Jan-2002  tsutsui branches: 1.10.8;
Call malloc(9) with M_ZERO flag instead of memset() after malloc().
 1.9  13-Nov-2001  lukem add/cleanup RCSIDs
 1.8  14-Sep-2001  ad Zero out uninitalized fields in the freshly allocated zs_chanstate.
 1.7  30-May-2001  lukem branches: 1.7.2; 1.7.4;
add missing #include "opt_kgdb.h"
 1.6  22-Nov-2000  nisimura branches: 1.6.2;
- fix an error in uninitialized variable reference.
- add a missing function argument declaration.
- minor comment adjustments.
 1.5  17-Oct-2000  nisimura branches: 1.5.2;
Have consistent #if's for machine dependent clauses.
 1.4  17-Oct-2000  nisimura - efforts to merge TC Alpha and IOASIC DECstation, derived from Mattias
Drochner's work made in nisimura-pmax-wscons branch. Still a little
to do before useful for DECstation. MI softintr required.
- allow wildcard matchs to have zstty/zskbd/zsms in default hardware
configuration.
- abandon to check zs_ioasic_cnattach() return value; it doesn't fail.
- have zs_ioasic_cnattach() serial line parameters hardcoded inside, in
symmetry with zs_ioasic_lk201_cnattach().
 1.3  09-Sep-2000  nisimura u_char -> u_int for function argument and return of Zilog register
manipulation helper functions; no loss, no gain, for Alpha processor.
 1.2  05-Jul-2000  nisimura - Withdraw ZS_IOASIC_DMA conditional which has never been useful.
- Sanitize ZS register access.
 1.1  05-Jul-2000  nisimura Repopulate 4 files, zs_ioasic.c and zs_ioasicvar.h from arch/alpha/tc,
zskbd.c and zsms.c from dev/dec/, respectively. No functionality
change this time.
 1.5.2.3  08-Dec-2000  bouyer Sync with HEAD.
 1.5.2.2  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

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.
 1.32.18.2  15-Jul-2007  ad Get pmax working.
 1.32.18.1  17-Jun-2007  ad - Increase the number of thread priorities from 128 to 256. How the space
is set up is to be revisited.
- Implement soft interrupts as kernel threads. A generic implementation
is provided, with hooks for fast-path MD code that can run the interrupt
threads over the top of other threads executing in the kernel.
- Split vnode::v_flag into three fields, depending on how the flag is
locked (by the interlock, by the vnode lock, by the file system).
- Miscellaneous locking fixes and improvements.
