e5979322ba Remove local hacks to set flags now that the device probe does this for us.
Tested on every device except sio_pci and the pc98 fd.c.  Perhaps something
similar should be done for the "disabled" hints also.

e04ed822be o Return ai_batteries as 0xffffffff instead of -1. This is a nop change, but
placates gcc which seems to like to complain about -1 being assigned to
  an unsigned value.  It is well defined and intended, but since signess bugs
  are being hunted just change to 0xffffffff.
o Mask the lower 8 bits, not the lower 4 bits for the ai_capabilities word.
  All 8 bits are defined and the 0xf was almost certainly a typo.
o Define APM_UNKNOWN to 0xff for emulation layer.

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

70cd771337 The present defaults for the open and close for device drivers which
provide no methods does not make any sense, and is not used by any
driver.

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.

Change the defaults to be nullopen() and nullclose() which simply
does nothing.

Remove explicit initializations to these from the drivers which
already used them.

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.

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.

899ccf541a Add generalized power profile code.
This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified
the events.

 - move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
 - call power_profile_set_state() also from APM driver when AC-line
   status changes
 - add call-back function for Crusoe LongRun controlling on power
   profile changes for a example

f9390180fe Some fix for the recent apm module changes.
- Now that apm loadable module can inform its existence to other kernel
   components  (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
 - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
 - Add simple arbitration mechanism for APM vs. ACPI.  This prevents
   the kernel enables both of them.
 - Remove obsolete `#ifdef DEV_APM' related code.
 - Add abstracted interface for Powermanagement operations.  Public apm(4)
   functions, such as apm_suspend(), should be replaced new interfaces.
   Currently only power_pm_suspend (successor of apm_suspend) is implemented.

2bfb7205bf Add Timer device driver for power management events.
The code for suspend/resume is derived from APM device driver.

Some people suggested the original code is somewhat buggy, but I'd
like to just move it from apm.c without any major changes for the
initial version.  This code should be refined later.

To use pmtimer to adjust time at resume time, add
	device	pmtimer
in your kernel config file, and add
	hint.pmtimer.0.at="isa"
in your device.hints

16422b76f1 Correctly handle suspend and resume in APM.
Up to now, errors from DEVICE_SUSPEND(root_bus) were ignored. The fix for
this problem (the introduction of defaults for device methods) has been
committed months ago by Doug Rabson.

Second, the suspended devices were not always properly resumed on error.

Third, swapped the order for calling restore hooks and restore methods, to
be in line with the cases above.
