a1fccb4765 Add device(power/sleep button and lid) wake function from sleeping state.
This is required for some Thinkpad (and maybe VAIO) machines to wake
the system up from sleep.

Currently partially implemented, more complete implementation will come later.

d786139c76 Rework the kernel environment subsystem. We now convert the static
environment needed at boot time to a dynamic subsystem when VM is
up.  The dynamic kernel environment is protected by an sx lock.

This adds some new functions to manipulate the kernel environment :
freeenv(), setenv(), unsetenv() and testenv().  freeenv() has to be
called after every getenv() when you have finished using the string.
testenv() only tests if an environment variable is present, and
doesn't require a freeenv() call. setenv() and unsetenv() are self
explanatory.

The kenv(2) syscall exports these new functionalities to userland,
mainly for kenv(1).

116caf7cf7 Hide the ACPI counter probing printf behind bootverbose.
The conclusion is that this method really can tell the perfect from the
less than perfect ACPI counters.

It is in fact probably a bit more discriminative than that, but we
will rather condemn some otherwise perfect counters to the slightly
slower "-safe" version, than certify a counter as perfect which
will let us down later.

Many thanks to all the people who sent email reports!

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

cb877d0050 Add a new test_counter() function which tries to determine the width of
the inter-value histogram for 2000 samples.  If the width is 3 or less
for 10 consequtive samples, we trust the counter to be good, otherwise
we use the *_safe() method.

This method may be too strict, but the worst which can happen is that
we take the performance hit of the *_safe() method when we should not.

Make the *_safe() method more discriminating by mandating that the three
samples do not span more than 15 ticks on the counter.

Disable the PCI-ident based probing as a means to recognize good
counters.

d32e27a9f4 Tests by numerous people have shown that many chipsets do not properly
latch the acpi timer, resulting in weird deltas.  The problem is severe
enough to adversely effect the timecounter code.

Default to the 'safe' version of the get-timecount function.  The probe
will override it if a known-good chipset is found.  This is temporary
until a more complete solution is found.

c86b6ff551 Change the preemption code for software interrupt thread schedules and
mutex releases to not require flags for the cases when preemption is
not allowed:

The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent
switching to a higher priority thread on mutex releease and swi schedule,
respectively when that switch is not safe.  Now that the critical section
API maintains a per-thread nesting count, the kernel can easily check
whether or not it should switch without relying on flags from the
programmer.  This fixes a few bugs in that all current callers of
swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from
fast interrupt handlers and the swi_sched of softclock needed this flag.
Note that to ensure that swi_sched()'s in clock and fast interrupt
handlers do not switch, these handlers have to be explicitly wrapped
in critical_enter/exit pairs.  Presently, just wrapping the handlers is
sufficient, but in the future with the fully preemptive kernel, the
interrupt must be EOI'd before critical_exit() is called.  (critical_exit()
can switch due to a deferred preemption in a fully preemptive kernel.)

I've tested the changes to the interrupt code on i386 and alpha.  I have
not tested ia64, but the interrupt code is almost identical to the alpha
code, so I expect it will work fine.  PowerPC and ARM do not yet have
interrupt code in the tree so they shouldn't be broken.  Sparc64 is
broken, but that's been ok'd by jake and tmm who will be fixing the
interrupt code for sparc64 shortly.

Wakeup event is generated by power button or sleep button on some
laptops but this also generates SCI interrupt, and shutdown the system
as result.  So this is introduced so that acpi driver ignore given
