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.

of the `machdep.acpi_root' sysctl. This is required on ia64
because the root pointer hardly ever, if at all, lives in the
first MB of memory and also because scanning the first MB of
memory can cause machine checks.
This provides a save and reliable way for ACPI tools to work
with the tables if ACPI support is present in the kernel. On
ia64 ACPI is non-optional.
macro for use when parsing MADT tables, thus we always tried to set the
interrupt model to APIC. This proved to be harmful on UP machines with
IO APIC's (or for UP kernels on SMP machines) since the wrong interrupt
routing information would be returned.

and attach routines have succeeded so that if they fail we can still use
the PnP BIOS to find ISA on-board devices. The fact that we do this here
is gross but fixing it properly involves a lot more work.
- clean up wakeup routing fixup code by using macros.
- allocate pte object temporary for kernel thread to avoid kernel
panic by events from sleep button or lid switch.
- Add S4BIOS sleep implementation. This will works well if MIB
hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
is enabled correctly).
- Add DSDT overriding support which is submitted by takawata originally.
If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
ACPI CA core loads DSDT from given file rather than BIOS memory block.
DSDT file can be generated by iasl in ports/devel/acpicatools/.
- Add new files so that we can add our proposed additional code to Intel
ACPI CA into these files temporary. They will be removed when
similar code is added into ACPI CA officially.
This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications. The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
- APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
- APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
- APMIO_GETINFO and APMIO_GETINFO_OLD
- APMIO_GETPWSTATUS
With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)
