 1.51  07-Sep-2023  ad Make the I2O management cdevs MPSAFE.
 1.50  03-Sep-2018  riastradh Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)
 1.49  28-Oct-2017  riastradh branches: 1.49.2; 1.49.4;
Kill some more extern struct cfdriver declarations.

Down with externs in .c!
 1.48  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.
 1.47  20-Mar-2014  christos branches: 1.47.2;
make this compile again.
XXX: 32 bit pointer issues.
 1.46  16-Mar-2014  dholland 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.
 1.45  27-Oct-2012  chs branches: 1.45.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.44  07-Aug-2011  rmind branches: 1.44.2; 1.44.12;
Replace some wakeup_one(9) uses with mutex(9) or plain wakeup(9).
 1.43  13-Nov-2010  uebayasi Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.
 1.42  12-May-2009  cegger branches: 1.42.4;
struct device * -> device_t, no functional changes intended.
 1.41  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.40  08-Sep-2008  gmcgarry branches: 1.40.8;

Replace some uses of lockmgr() / simplelocks.
 1.31  02-Dec-2006  elad Change kauth(9) KPI for kauth_authorize_device_passthru() to add another
argument, u_long, serving as a bit-mask of generic requests for the
passthru request.

Discussed on tech-security@ and tech-kern@. Okay tls@.
 1.30  16-Nov-2006  christos branches: 1.30.2;
__unused removal on arguments; approved by core.
 1.29  08-Nov-2006  elad Replace securelevel checks with kauth(9) calls.

 1.25  23-Aug-2006  christos Acting as Elad's keyboard:

Place the securelevel checks in their logical locations.
This will be clearer in the future when code changes to use kauth(9) calls.

input and okay ad@
 1.24  29-Mar-2006  thorpej Use device_private().
 1.23  28-Mar-2006  thorpej Use device_unit().
 1.22  25-Mar-2006  thorpej Use device_parent().
 1.21  11-Dec-2005  christos branches: 1.21.4; 1.21.6; 1.21.8; 1.21.10; 1.21.12;
merge ktrace-lwp.
 1.20  24-Nov-2005  fredb Initialize "mapped" before any of the "goto"'s, so we're not testing an
uninitialized variable at "bad:".
 1.19  27-Feb-2005  perry branches: 1.19.4; 1.19.10;
nuke trailing whitespace
 1.18  22-Apr-2004  itojun branches: 1.18.4; 1.18.6;
sprintf -> snprintf
 1.17  09-Dec-2003  ad Grab the configuration lock when handling I2ORESCANCMD.
 1.16  30-Oct-2003  simonb Remove some assigned-to but otherwise unused variables.
 1.15  29-Oct-2003  mycroft Reorder, eliminating a bogus initializer.
 1.14  25-Oct-2003  christos Fix uninitialized variable warnings
 1.13  29-Jun-2003  fvdl branches: 1.13.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
 1.12  28-Jun-2003  darrenr Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
 1.11  14-Feb-2003  thorpej __'ify MACHINE_ARCH names.
 1.10  06-Dec-2002  ad - Handle DPT ioctls from native NetBSD binaries.
- SCSI targets could disapper mid-way through autoconfig if the board
notifed us of a changed LCT at the wrong time. Fix that.
 1.9  23-Oct-2002  jdolecek merge kqueue branch into -current

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
 1.8  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.7  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.6  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.5  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.
 1.4  31-May-2002  thorpej Use __mips__ instead of mips.
 1.3  13-Nov-2001  lukem branches: 1.3.2; 1.3.4; 1.3.12; 1.3.14;

Make firmware updates work with dpti.
 1.1  21-Sep-2001  ad branches: 1.1.2;
Add `dpti', which is an I2O vendor extension implementing the DPT/Adaptec
control interface. This makes it possible to run the Linux versions of
dptmgr, raidutil, dptelog and other tools under NetBSD.

Hi Perry!
 1.13.2.4  21-Sep-2004  skrll Fix the sync with head I botched.

 1.13.2.1  02-Jul-2003  darrenr Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

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

 1.35.16.1  05-Apr-2008  mjf - add "file-system DEVFS" and "pseudo-device devfsctl" to conf/std seeing
as these are always needed.

- convert many, many drivers over to the New Devfs World Order. For a
list of device drivers yet to be converted see,
http://www.netbsd.org/~mjf/devfs-todo.html.

- add a new device_unregister_all(device_t) function to remove all device
names associated with a device_t, which saves us having to construct
device names when the driver is detached.

- add a DEV_AUDIO type for devices.
