Any modifications to SYSTEM_OBJS after including kern.post.mk
will not make it to SYSTEM_DEP and consequently any dependency
rules. This caused __{div|rem}* to not be built...
- 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.

Fix it by putting back the link of machine to sys/i386/include rather

kern.post.mk, which contains most of the rules.
I've tested this on i386 and pc98. I have had feedback on the sparc64

appologize in advance if I've broken you.

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 :-)

Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested. Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.
This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().
It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".
The type of bus_space_tag_t is now a pointer to bus_space_tag structure,
and the bus_space_tag structure saves pointers to functions for direct

Added bsh_bam member to the bus_space_handle structure, it saves access
method either direct access or relocate access which is called by
bus_space_* functions.
Added the mecia device support. If the bs_da and bs_ra in bus tag are set
NEPC_io_space_tag and NEPC_mem_space_tag respectively, new bus_space stuff
changes the register of mecia automatically for 16bit access.
