Remove FreeBSD blocks that did not compile anyway, and use l->l_cred
consistently.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

branches: 1.20.2;
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.

branches: 1.19.76; 1.19.86; 1.19.92;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.18.4;
Kill some KAUTH_GENERIC_ISSUSER.

Merge the peter-altq branch.

(sync with KAME & add support for using ALTQ with pf(4)).

branches: 1.16.2; 1.16.4;
add missing initializer

- Use the LWP cached credentials where sane.
- Minor cosmetic changes.

kauth fallout

integrate kauth.

merge ktrace-lwp.

branches: 1.11.4;
nuke trailing whitespace

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

pull only "opt_altq_enabled.h" in if_altq.h, and include altqconf.h
explicitly in single file which implicitly needed it (altq_conf.c)

this avoids pulling in implicit dependency on <sys/conf.h> to every
file including <net/if.h> (which includes <altq/if_altq.h> to get altq
related structures)

make this compile.

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.

branches: 1.6.6;
bring in latest ALTQ from kjc. ALTQify some of the drivers.

add RCSIDs

branches: 1.4.2; 1.4.4; 1.4.6; 1.4.8;
Saner glue into cdevsw.

No need to wrap these in #ifdef ALTQ -- they're not even included
if ALTQ is not configured into the kernel.

Add NetBSD RCS IDs.
