51da11a27a Fix some easy, global, lint warnings. In most cases, this means
making some local variables static. In a couple of cases, this means
removing an unused variable.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

85f190e4d1 Fixes to make select/poll mpsafe.
Problem:
  selwakeup required calling pfind which would cause lock order
  reversals with the allproc_lock and the per-process filedesc lock.
Solution:
  Instead of recording the pid of the select()'ing process into the
  selinfo structure, actually record a pointer to the thread.  To
  avoid dereferencing a bad address all the selinfo structures that
  are in use by a thread are kept in a list hung off the thread
  (protected by sellock).  When a selwakeup occurs the selinfo is
  removed from that threads list, it is also removed on the way out
  of select or poll where the thread will traverse its list removing
  all the selinfos from its own list.

Problem:
  Previously the PROC_LOCK was used to provide the mutual exclusion
  needed to ensure proper locking, this couldn't work because there
  was a single condvar used for select and poll and condvars can
  only be used with a single mutex.
Solution:
  Introduce a global mutex 'sellock' which is used to provide mutual
  exclusion when recording events to wait on as well as performing
  notification when an event occurs.

Interesting note:
  schedlock is required to manipulate the per-thread TDF_SELECT
  flag, however if given its own field it would not need schedlock,
  also because TDF_SELECT is only manipulated under sellock one
  doesn't actually use schedlock for syncronization, only to protect
  against corruption.

Proc locks are no longer used in select/poll.

8166ba27bd Hack for the "out-of-sync" error.
- Count the number of this error.
- When the error is detected for the first time, the psm driver will
  throw few data bytes (up to entire packet size) and see if it can
  get back to sync.
- If the error still persists, the psm driver disable/enable the mouse
  and see if it works.
- If the error still persists and the count goes up to 20,
  the psm driver reset and reinitialize the mouse. The counter
  is reset to zero.
- It also discards an incomplete data packet when the interval
  between two consequtive bytes are longer than pre-defined timeout
  (2 seconds).  The last byte which arrived late will be regarded as
  the first byte of a new packet.  This is louie's idea.

You may see the following error logs during the above operations:

  "psmintr: delay too long; resetting byte count"
  "psmintr: out of sync (%04x != %04x)"
  "psmintr: discard a byte (%d)"
  "psmintr: re-enable the mouse"
  "psmintr: reset the mouse"

cd6cd68d18 Refine ACPI/PnP BIOS probe/attach routines a bit.
- Add workaround for the problematic PnP BIOS which does not assign
  irq resource for the PS/2 mouse device node; if there is no irq
  assigned for the PS/2 mouse node, refer to device.hints for an
  irq number. If we still don't find an irq number in the hints
  database, use a hard-coded value.
- Delete unused ivars.
- Bit of clean up in probe/attach.
- Add PnP ID for the PS/2 mouse port on some IBM ThinkPad models.

make the kernel aware that there are smaller units of scheduling than the

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

872dfb2dd3 - Add a hack for "psmintr: out of sync.." This is NOT a fix,
but a hack! Add `flags 0x8000' to the psm driver to enable it.
  The psm driver will try to get out of out-of-sync situation
  by disabling the mouse and immediately enable it again.

If you are seeing this out-of-sync problem because of an
incompetent(?!) KVM switch, this hack will NOT be good
for you.  However, if you are occasionally seeing the
problem because of lost mouse interrupt, this might help.

3346e881c1 - Add Support for the following PS/2 mice:
- Microsoft IntelliMouse Explorer: 2 buttons on top, 2 side buttons
    and a wheel which also acts as the middle button.  The mouse is
    recognized as "IntelliMouse Explorer".
  - Genius NetScroll Optical: 2 buttons on top, 2 side buttons and a
    wheel which also acts as the middle button.  The mouse is recognized
    as "NetMouse/NetScroll Optical".
  - MouseSystems SmartScroll Mouse (OEM from Genius?): 3 buttons on top,
    1 side button and a wheel.  The mouse is recognized as Genius
    "NetScroll".
  - IBM ScrollPoint: 2 buttons on top and a stick between the buttons.
    The stick can perform "horizontal scroll" in W*ndows environment.
    The horizontal movement of the stick is detected.  It is currently
    mapped to the Z axis movement in the same way as the first wheel.
    The mouse is recognized as "MouseMan+", as it is considered to be
    a variation of MouseMan.
  - A4 Tech 4D and 4D+ mice. These mice have two wheels! The movement
    of the second wheel is reported as the Z axis movement in the
    same way as the first wheel. These mice are recognized as "4D
    Mouse" and "4D+ Mouse".
  - Tweak IntelliMouse support code a bit so that less-than-compatible
    wheel mice can work properly with the psm driver.
- Add driver configuration flags which correspond to the kernel
  options PSM_HOOKRESUME and PSM_RESETAFTERSUSPEND, so that we don't
  need to recompile the kernel when we need these functions.
- Properly keep track of the irq resource.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().
