d168d95487 Integrate kbdmux(4) into syscons(4) and kbd code.
By default syscons(4) will look for the kbdmux(4) keyboard first, and then,
if not found, look for any keyboard.

Current kbd code is modified so if kbdmux(4) is the current keyboard, all
new keyboards are automatically added to the kbdmux(4).

Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at
the loader prompt, or at runtime, by kldload'ing the kbdmux module and
releasing current active keyboard.

If, for whatever reason, kbdmux(4) is not required/desired then just do
not load it and everything should work as before. It is also possible to
kldunload kbdmux at runtime and syscons(4) will automatically switch to
the first available keyboard.

04551c6ce5 kbdmux(4) keyboard multiplexer integration
o Add two new ioctl's KBADDKBD and KBRELKBD. These are used to add and remove
  keyboard to (and from) kbdmux(4) keyboard multiplexer;

o Introduce new kbd_find_keyboard2() function. It does exactly the same job
  as kbd_find_keyboard() function except it allows to specify starting index.
  This function can be used to iterate over keyboards array;

o Re-implement kbd_find_keyboard() as call to kbd_find_keyboard2() with starting
  index of zero;

o Make sure syscons(4) passed KBADDKBD and KBRELKBD ioctl's onto currently
  active keyboard.

These changes should not have any visible effect.

520b635320 - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
  atkbdc(4) and its children were moved to the new location in preparation
  for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
  order to not further scatter them over the whole tree which would have
  been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
  reason for the repo-copies was that some of the sources were misfiled,
  e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
  atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
  Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
  ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
  but are shareable between different atkbdc(4) bus front-ends into
  atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
  bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
  respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
  atkbdc(4). PS/2 controllers and input devices are used on a couple of
  Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
  the board it's either the only on-board mean to connect a keyboard and
  mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
  without isa(4) (e.g. for EBus-only machines). This ISA-specific part
  isn't separated into its own source file, yet, as it requires more work
  than was feasible for 6.0 in order to do it in a clean way. Actually
  philip@ is working on a rewrite of psm(4) so a more comprehensive
  clean-up and separation of hardware dependent and independent parts is
  expected to happen after 6.0.

This command causes problems with some non-compliant hardware, resulting

823261a3e1 While USB keyboards attach as ukbd[0-9]+, the device node created by
kbd_attach() is called kbd[0-9]+, with a different unit number.  This
makes it impossible to write a devd rule which will automatically
switch to a USB keyboard when one is attached, because there is no way
to guess the correct device node to pass to kbdcontrol.

Therefore, change kbd_attach() to create a device node using the
keyboard device's real name (atkbd0, ukbd0...), and create the
kbd[0-9]+ node as an alias for backward compatibility.

8a9bc9c03b - Use the new resource_disabled() helper function to see if devices are
disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
  see if the device is disabled in the identify routine instead of in the
  probe routine.  This way if the device is disabled it is never created.

Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled".  If this is a big problem, resource_disabled() can always be
changed to honor both names.

fca9a10bc1 Add a a sysctl, hw.kbd.keymap_restrict_change, which acts a bit
like secure level but which restricts changes to the keymap. Its
values impose the following restrictions:

0: No restriction - this is the default.
1: Only root can change restricted keys (like boot, panic, ...)
2: Only root can change restricted keys and regular keys.
   Other users still can change accents and function keys.
3: Only root can change restricted keys, regular keys and accents.
4: Only root can change any of the keymap (restricted keys, regular
      keys, accents and function keys).

Unfortunately, the keyboard's accent map is cleared when a new keymap
is loaded, which makes the distinction between level 3 and level 4
less useful.

The MAC guys might like to make this a policy?

fb9da1ef43 Include "opt_kbd.h" since certain structures size depend on the value
of KBDIO_DEBUG which may be defined in the kernel config (as it is in NOTES).

This kind of bug is a _really_ horribly thing as we end up with one bit
of code thinking a particular structure is 136 bytes and another that it
is only 112 bytes.

Ideally all places would remember to #include the right "opt_foo.h" file,
but I think in practice file containing the variable sized struct should
#include it explicitly as a precaution.

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.

f41325db5f With this commit, I hereby pronounce gensetdefs past its use-by date.
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible.  <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set.  They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>).  Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated.  This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.
