 1.37  12-Aug-2021  andvar fix various typos in comments.
 1.36  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.35  24-Apr-2021  thorpej branches: 1.35.8;
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?).
 1.34  29-Oct-2019  christos branches: 1.34.10;
Implement what the documentation in rfreg.h states, and do not apply the
wrong mask to the command register (which kind of works, but really?!?!)
Found by gcc -Wtautological-compare
 1.33  08-Dec-2015  christos branches: 1.33.18;
Replace DIOCGPART -> DIOCGPARTINFO which returns the data needed instead of
pointers.
 1.32  26-Apr-2015  mlelstv Use C99-style initializers for struct dkdriver.
 1.31  02-Jan-2015  christos We have three sets of DTYPE_ constants in the kernel:
altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
 1.30  31-Dec-2014  christos make more drivers use disk_ioctl, and add a dev parameter to it so that
we can merge the "easy" disklabel ioctls to it. Ultimately all this will
go do dk_ioctl once all the drivers have been converted.
 1.29  04-Aug-2014  ryoon branches: 1.29.4;
Fix typo in comment.
 1.28  25-Jul-2014  dholland Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.27  25-Jul-2014  dholland Add d_discard to all struct bdevsw instances I could find.

I've set them all to nodiscard. Some of them (wd, dk, vnd, ld,
raidframe, maybe cgd) should be implemented for real.
 1.26  16-Mar-2014  dholland branches: 1.26.2;
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.
 1.25  27-Oct-2012  chs branches: 1.25.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.24  22-Jan-2009  cegger branches: 1.24.14; 1.24.24;
buildfix: re-adapt to major()/minor() return a 32bit value again.
 1.23  13-Jan-2009  yamt g/c BUFQ_FOO() macros and use bufq_foo() directly.
 1.22  12-Jan-2009  cegger use PRIu64 format to printf DISKPART
 1.21  25-Jul-2008  dsl branches: 1.21.2;
Replace a 'do { ... } while (0);' with 'for (;;) { ... break; }'
so that the 'continue' has the (probably) desired effect.
 1.20  15-Mar-2008  jkunz branches: 1.20.4; 1.20.6; 1.20.8; 1.20.10;
Use device_* accessors.
 1.19  11-Mar-2008  matt Rototill the vax code. Switch to devicet/PRIV_ALLOC. Cleanup vax autoconf
code. Move to prototype definitions. staticfy, constify, avoid casting.
Use device_* accessors.
 1.18  04-Jan-2008  joerg branches: 1.18.2; 1.18.6;
Catch up with rename of buf's b_un.b_addr -> b_data.
 1.17  19-Oct-2007  ad branches: 1.17.2; 1.17.8;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.16  08-Oct-2007  ad branches: 1.16.2;
Merge disk init changes from the vmlocking branch. These seperate init /
destroy of 'struct disk' from attach / detach.
 1.15  29-Jul-2007  ad branches: 1.15.4; 1.15.6; 1.15.8; 1.15.10;
It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.
 1.14  08-Mar-2007  he branches: 1.14.2; 1.14.6; 1.14.10;
Cast to char* before doing pointer arithmetic.
 1.13  04-Mar-2007  christos Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.12  29-Mar-2006  thorpej branches: 1.12.14;
Use device_private().
 1.11  25-Mar-2006  thorpej Use device_parent().
 1.10  11-Dec-2005  christos branches: 1.10.4; 1.10.6; 1.10.8; 1.10.10; 1.10.12;
merge ktrace-lwp.
 1.9  15-Oct-2005  yamt - change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
 1.8  26-Feb-2005  simonb branches: 1.8.4;
White space nits.
 1.7  28-Oct-2004  yamt branches: 1.7.4; 1.7.6;

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.
