0aad0f2282 These are the things that the tinderbox has problems with because it
doesn't use the default CFLAGS which contain -fno-strict-aliasing.

Until the code is cleaned up, just add -fno-strict-aliasing to the
CFLAGS of these for the tinderboxes' sake, allowing the rest of the
tree to have -Werror enabled again.

c44b9f1811 Fix acpidump(8) on ia64. Revision 1.13 introduced an uninitialized
variable bug that's hidden by the precense of the hint_acpi_0_rsdp
hint on 386 and amd64. There's never a need for such hint on ia64.

00a304487f Update the suspend/resume user API while maintaining backwards compat.
Improvements:
* /etc/rc.suspend,rc.resume are always run, no matter the source of the
  suspend request (user or kernel, apm or acpi)
* suspend now requires positive user acknowledgement.  If a user program
  wants to cancel the suspend, they can.  If one of the user programs
  hangs or doesn't respond within 10 seconds, the system suspends anyway.
* /dev/apm is clonable, allowing multiple listeners for suspend events.
  In the future, xorg-server can use this to be informed about suspend
  even if there are other listeners (i.e. apmd).

Changes:
* Two new ACPI ioctls:  REQSLPSTATE and ACKSLPSTATE.  Request begins the
  process of suspending by notifying all listeners.  acpi is monitored by
  devd(8) and /dev/apm listener(s) are also counted.  Users register their
  approval or disapproval via Ack.  If anyone disapproves, suspend is vetoed.
* Old user programs or kernel modules that used SETSLPSTATE continue to
  work.  A message is printed once that this interface is deprecated.
* acpiconf gains the -k flag to ack the suspend request.  This flag is
  undocumented on purpose since it's only used by /etc/rc.suspend.  It is
  not intended to be a permanent change and will be removed once a better
  power API is implemented.
* S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z.
  This restores previous behavior of halt/shutdown -p being the interface.
* Miscellaneous improvements to error reporting

bfccea1e5d o Report charge/discharge rate and remaining capacity in the proper
units (as specified in _BIF). (noted by Bruno Ducrot)
o In looking in the standard, if the cap numbers are 0xffffffff, then acpi
  is reporting unknown for that field.  Report unknown numbers properly.

62c7bde198 Add the -s flag to make dumping SSDTs optional (disabled by default).
Since we can only override the DSDT, a custom ASL dumped previously that
contained SSDTs would result in lots of multiple definition errors.

A longer-term fix involves adding the ability to override SSDTs to ACPI-CA.

5cf6d493ab When one entry in the RSDT is corrupted, just skip it instead of bailing out.
This gets us the info we need on systems which have proprietary tables that
don't match the standard.  For instance, an AMI system has a table of type
"OEMB" with an invalid checksum.

e079f9491a Remove the ACPIIO_ENABLE and ACPIIO_DISABLE ioctls as well as all
callers.  These ioctls attempted to enable and disable the ACPI
interpreter at runtime.  In practice, it is not possible to boot with
ACPI and then disable it on many systems and trying to do so can cause
crashes, interrupt storms, etc.  Binary compatibility with userland is
retained.

7611a6dcd6 We now handle SSDT tables. Remove a reference from the BUGS section
and explicitly mention SSDT when we talk about the DSDT so that people
don't have to guess whether it includes the SSDT.

bfa3f012cd Add support for SSDT tables. Dumping or disassembling the DSDT will
now include the contents if any SSDT table as well. This makes use
of the property that one can concatenate the body of SSDT tables to
the DSDT, updating the DSDT header (length and checksum) and end up
with a larger and valid DSDT table. Hence, this also works with -f.

8fc0f4c675 Instead of scanning the entire lower 1 MB of RAM, only scan locations
where the RSD PTR can actually occur.  According to section 5.2.2
of the ACPI spec, we only consider two regions for the base address:

    1. EBDA (0x0 - 0x3FF)
    2. High memory (0xE0000 - 0xFFFFF)

I don't know whether this fixes any actual problems but is more correct.
