fix various typos in bktr driver comments.

Move proc_lock into the data segment.  It was dynamically allocated because
at the time we had mutex_obj_alloc() but not __cacheline_aligned.

- add or adjust /* FALLTHROUGH */ where appropriate
- add __unreachable() after functions that can return but won't in
  this case, and thus can't be marked __dead easily

Resolve a couple of conflicts (result of the uimin/uimax changes)

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macppc/if_gm.c (superseded by gem(4))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!)

bt848_format is only defined in a __FreeBSD__ section of bktr_os.c and
overriding the local (static) definition with extern is bogus.

Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

Welcome to 4.99.55:

- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call.  It will
  indicate which event (POLL_IN, POLL_OUT, etc) happen.  If unknown,
  zero may be used.

Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>

Start detangling lock.h from intr.h. This is likely to cause short term
breakage, but the mess of dependencies has been regularly breaking the
build recently anyhow.

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

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

Changes to select/poll:

- Make them MP safe and decouple from the proc locks.
- selwakeup: don't call p_find, or traverse per-proc LWP lists (ouch).
- selwakeup: don't lock the sleep queue unless we need to.

Fix the sync with head I botched.

Sync with HEAD.

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.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

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

DMA, not dma nor Dma.

Quell a strict-alias warning by applying the same cast to '&target' as
already done in all other cases.

Merge some more.

Merge first bktr-sf import.

Import of current state of bktr(4) in sourceforge repository.
Changes since last import:
. lots of whitespace cleanups
. typo fixes (e.g. hz, compatibilty)
. fix brightness ioctl return value
. wait for int ready using DELAY() instead of tight loop

Sync with HEAD.

Make this work on big endian platforms (mostly from OpenBSD):
Uploaded scripts work better if they are little endian, as the
card's engine expects, so convert to le first.

Also clean up attach routine a bit (use pa_id and PCI_REVISION
instead of fetching it ourselves).

This makes the driver work on my macppc G4, it can decode and
display video and tuner input. Sound does not seem to work, but
this may be my wonky formac bktr-for-macintosh card.

Fix broken programming of VSCALE_HI registers in yuv422_prog.

Consistently use BKTR_GEN_IRQ and BKTR_RESYNC instead of numbers.
Also, do some whitespace cleanup.

Merge 2.18 to trunk.

Import release 2.18 of the bktr driver. Changes since 2.17:
o Add new ioctls to allow userland programs fuller access to the I2C
  bus, BT848_MSP_READ BT848_MSP_WRITE and BT848_MSP_RESET.
o Add tuner type 0x2a. Remove 0x2c which was incorrect.
o Christian Gusenbauer <Christian.Gusenbauer@netway.at> added support
  for audio on Hauppauge cards without the audio mux. The MSP is used
  for audio selection. (the 44xxx models)

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.

file bktr_core.c was added on branch thorpej_scsipi on 2000-11-20 22:35:46 +0000

Replace remaining vm_offset_t's in NetBSD code by vaddr_t; remove now

Merge 2.17 changes to trunk.

Import release 2.17 of the bktr driver.
Changes: Integration of some NetBSD changes. (FreeBSD version now is also

	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

Replaced overlooked BROOKTREE_SYSTEM_DEFAULT with BKTR_SYSTEM_DEFAULT,
as noted by Roger Hardiman.

Use bktr_softc.bktr_dev.dv_xname instead of "bktr0" when printf'ing as
requested by Klaus Klein in kern/10166.
Also add device instance name to all printf's that didn't have it.

It is a bad idea to declare a static bootverbose variable here. Remove it.

Import of (finally busspaced) bktr-driver from FreeBSD (part 1).
