Sync with HEAD

Add missing FALLTHROUGH in gpib/mt.c

Requested by GCC in NetBSD/i386 kUBSan KCOV build.

update from HEAD

Kill some more extern struct cfdriver declarations.

Down with externs in .c!

Sync with HEAD

- Use aprint*() instead of printf() in xxx_attach().
- Add missing aprint_naive("\n");
- KNF

Rebase to HEAD as of a few days ago.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

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

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.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

sync with head

remove unused

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.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Remove clause 3 (UCB advertising clause) from the University of Utah
copyright.  Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.

Extra verification by snj@.

sync with head

Convert tsleep(&lbolt) to kpause().  Make ltsleep/mtsleep on lbolt
illegal.  I examined all places where lbolt is referenced to make
sure there were pointer aliases of it passed to tsleep, but put a
KASSERT in m/ltsleep() just to be sure.

Fix warnings of printf(9) format.

Don't pass a buffer to physio(), let it be allocated dynamically.

This leaves only scsipi and atapi doing the same.

Commit is split, to avoid a "too many arguments" protocol error.

struct device * -> device_t, no functional changes intended.

struct cfdata * -> cfdata_t, no functional changes intended.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

- Back out the biodone() changes.
- Eliminate B_ERROR (from HEAD).

Sync with HEAD.

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.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

Adapt to callout API change.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

Rename the B_XXX flag to B_DEVPRIVATE flag since it was never used for
debugging and its main use is in device drivers. Its used there to signal
that the flagged buffer has a special meaning or should be handled
differently.

OK'd by Bill Sudenmund on tech-kern.

Complete initializers, teach drivers that we moved from struct proc to
struct lwp, sprinkle some needed const qualifiers.

Merge 2006-03-31 NetBSD-current into the "peter-altq" branch.

Use device_private().

merge ktrace-lwp.

Sync with HEAD. Here we go again...

- 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)

Sync with HEAD.

move buffer queue related stuffs from buf.h to their own header, bufq.h.

Fix the sync with head I botched.

Move UCB-licensed code from 4-clause to 3-clause licence.
