fec4b62adf Add another PS/2 keyboard PNP ID. This ID is listed as
"Reserved by Microsoft" in the standard PNP ID table, but has been seen
in the wild on at least one laptop.

a11df0cbe6 Only use the BIOS-supplied IRQ for the atkbdc device for a child atkbd

ce7a3e4774 - If the atkbdc device is assigned an IRQ resource by ACPI or the PnPBIOS,
allow the child atkbd device to reuse that IRQ resource instead of
  reallocating the same IRQ from the parent bus inside the atkbd driver.
- Don't allocate a shared IRQ for the atkbd driver.  For AT keyboard
  devices on an ISA bus the IRQ is not shareable.  Instead, the bus driver
  should mark the IRQ shareable if the bus supports shared IRQs.
- Don't identify child devices until after the atkbdc device itself has
  attached.

3d844eddb7 bus_add_child: change type of order parameter to u_int
This reflects actual type used to store and compare child device orders.
Change is mostly done via a Coccinelle (soon to be devel/coccinelle)
semantic patch.
Verified by LINT+modules kernel builds.

ff605594dd On certain chipsets AT keyboard controller isn't present and is
emulated by BIOS using SMI interrupt. On those chipsets reading
from the status port may be thousand times slower than usually.
Sometimes this emilation is not working properly resulting in
commands timing out and since we assume that inb() operation
takes very little time to complete we need to adjust number of
retries to keep waiting time within a designed limits (100ms).
Measure time it takes to make read_status() call and adjust
number of retries accordingly.

To keep it simple, use TSC to measure inb() performance and
keep it to amd64-only, since TSC may not available on older
CPUs.

Also enable detection of the AT controller absence on amd64.

6621aa5cc7 Use the same method for detecting actual presence of AT-style keyboard
controller as we use in boot blocks (querying status register until
bit 1 goes off). If that doesn't happed during reasonable period assume
that the hardware doesn't have AT-style keyboard controller. This makes
FreeBSD working almost OOB on MacBook Pro (still there are issues with
putting second CPU core on-line, but since installation CD comes with
UP kernel with this change one should be able to install FreeBSD without
playing tricks with hints). Other legacy-free hardware (e.g. IBM NetVista
S40) should benefit from this as well, but since I don't have any I can't
verify.

It should make no difference on the ordinary i386 hardware (since in
that case that hardware already would be having an issues with A20
routines in boot blocks). I don't know much about AT-style keyboard
controller on other platforms (and don't have dedicated access to one),
therefore, the code is restricted to i386 for now. I suspect that amd64
may need this as well, but I would rather leave this decision to someone
who knows better about the platform(s) in question.

I have tested this change on as many "ordinary i386 boxes" as I can get
my hands on, and it doesn't create any false negatives on hardware with
AT-style keyboard present.

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.

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.

- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather

  fallback to using strings before malloc/vm was running anyway.

3aae7b16d2 Fixed the type of some ivar access functions. Ivars have type uintptr_t,
not u_long.  On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().

fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

15317dd875 Alter the behavior of sys/kern/subr_bus.c:device_print_child()
- device_print_child() either lets the BUS_PRINT_CHILD
	  method produce the entire device announcement message or
	  it prints "foo0: not found\n"

Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)

Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

	- Devices are 'on' a bus, not 'at' it.
	- If a custom BUS_PRINT_CHILD method does the same thing
	  as bus_generic_print_child(), use bus_generic_print_child()
	- Use device_get_nameunit() instead of both
	  device_get_name() and device_get_unit()
	- All BUS_PRINT_CHILD methods return the number of
	  characters output.
