By this change, ACPI debugger/disassembler are only
compiled when both DDB and ACPI_DEBUG options are
specified. This change also reduces the kernel size
a little when ACPI_DEBUG is not specified.

Thanks for jhb@freebsd to find out this problem.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
which gives problems with PCI bus finding; the object hierarchy doesn't
match the real world for some systems, most notably SuperMicro boards.
Linux has this one blacklisted as well.
Right now, only power switch state change events are supported. This
is a work-in-progress.
* Add support to sysmon for delivering power mangement events to userland.
Add poll, kqueue, and read entry points to sysmon.
* Adapt ACPI to use the new generic <sys/power.h> event types.
This provides the kernel support for a forthcoming powerd(8) which can
do nice things like gracefully shut the system down when an ACPI power
button is pressed.
the kernel config file. That code makes a total mess of any
system with multiple PCI busses.
* Rework the way buttons are handled; register them with sysmon,
and let it take the appropriate action. This lets us gracefully
shut down when the power button is pressed.
- make sure that the driver checks the battery presence at acpibat_update()
if the battery has been not present, because the driver sometimes
(i.e. boot time or resuming time) miss to sense the presence.
- make sure that the driver always update the status at acpibat_gtredata();
I misunderstood about ACPI_NOTIFY_BatteryStatusChanged event.
it is very slow to access to EC on some machines (i.e. CASIO FIVA 2xx).
- clean the flags up.
- add locks while updating informations.
- some cosmetic changes.
acpi_is_global_locked() functions.
AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
This API cannot be used to lock between threads of the OS side,
because this function immediately returns if the lock is already acquired
by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c
- make sure that acpiec driver uses above functions.
- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),
in acpi_eval_string()/acpi_eval_struct().
Twice AcpiEvaluateObject() calls may cause twice side effects
to ACPI machine / hardware and this may be wrong in some cases.
