cd85e2620d Small correction in the LOCAL_SAPIC structure. The Flags field
starts at offset 8; not 6. Hence the structure is 12 bytes and
not 10 bytes. Adjust the definition so that the ProcessorEnabled
flag is moved from bit 15 to bit 31 in the Flags field.

The definition now matches ACPI 2.0 Errata 1.5.

229778f87e o Do not parse the MADT as a side-effect in AcpiOsGetRootPointer,
do it as a side-effect of probing for MP hardware. This allows
   us to scan for local SAPICs early (especially before MBUF
   initialization).
o  Fix the Local SAPIC structure so that matches the Local SAPIC
   table entry. Now that the Local SAPIC info is the same as the
   Local APIC info, stop dumping the Local APIC entries.
o  For every Local SAPIC entry in the MADT that's not disabled,
   let the SMP code know about it. They represent actual CPUs.
o  Register the OS_BOOT_RENDEZ entry point and provide a (bogus)
   implementation for the entry point.
o  Provide a mapping for internal IPI numbers to ExtINT vectors.
o  In a MP system, announce the CPUs and start them by sending
   IPI_AP_WAKEUP to each of them. Not that it makes a difference
   at this time :-)
o  Miscellaneous style fixes and other adjustments.

f86214b6b8 Add APM compatibility feature to ACPI.
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 :-)

39a4abbe0c Add parse functions for local APIC and I/O APIC entries.
Also, show when a local APIC or SAPIC is disabled.

7a7029581c Wire up most of the interrupt handling infrastructure. Not sure it works
right yet but its enough for the ATA probe to work. The SCSI probes which
follow are broken though.

1676303c5c Add low-level ACPI support code and make a start on parsing the ACPI
interrupt information.
