Implement this in acpi_MatchHid() and acpi_isa_get_compatid(). This
should fix mouse support for some users.
Move all users of AcpiGetObjectInfo() to use dynamic storage instead of
a devinfo on the stack. This is necessary since ACPI-CA needs to
allocate different sized arrays for the CompatList.
throttling values being available regardless of the CPU's capabilities.
This has been broken since rev 1.1. Also clarify a comment.

- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of
using a statically sized array that depended on 'options SMP'.
- Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a
match.
- Always call smp_rendezvous() since UP kernels now provide this.
- Use mp_ncpus rather than cpu_ndevices when determining if we need to
disable C3 for SMP machines.

idx'th present CPU with pc_acpi_id equal to *acpi_id. If *acpi_id
does not match that processor's pc_acpi_id, return the value for
ProcId derived from the MADT in *acpi_id. If pc_acpi_id is 0xffffffff,
always override it with the value of *acpi_id. Finally, return
pc_cpuid in *cpu_id and use that as our primary key.
* Use pc_cpuid as our unique key because we know it is valid since
MD code set it. The values for ProcId in the ASL and MADT don't
match up on some machines (!), forcing us to fall back to ordered
probing in that case.
* Remove some #ifdef SMP since the refcount doesn't hurt performance
and will be needed for dynamic _CST objects. Only one #ifdef SMP
(for smp_rendezvous) remains.
* Hook up SMP in the compile flags in the Makefile.

boot-disabled devices instead of skipping the last interrupt. This is
especially important for devices that only have one interrupt as this
bug was keeping any interrupt from being tried at all.

an acpi_cpu method for shutdown that disables entry to acpi_cpu_idle
and then IPIs/waits for threads to exit. This fixes a panic late in
reboot in the SMP case.
* In the !SMP case, don't use the processor id filled out by the MADT
since there can only be one processor. This was causing a panic in
acpi_cpu_idle if the id was 1 since the data was being dereferenced from
cpu_softc[1] even though the actual data was in cpu_softc[0] (which is
correct).
* Rework the initialization functions so that cpu_idle_hook is written
late in the boot process.
* Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables.
This will help SMP boxes that have _CST or multiple P_BLKs. No such
boxes are known at this time.
* Always allocate the C1 state, even if the P_BLK is invalid. This means
we will always take over idling if enabled. Remove the value -1 as
valid for cx_lowest since this is redundant with machdep.cpu_idle_hlt.
* Reduce locking for the throttle initialization case to around the write
to the smi_cmd port. Add disabled code to write the CST_CNT. It will
be enabled once _CST re-evaluation is tested (post 5.2R).

* Use the cpu_idle_hook() to do idling for C1-C3.
* Use both _CST and the FADT to detect Cx states.
* Use both _PTC and P_CNT for controlling throttling.
* Add a notify handler to detect changes in _CST and _PSS
* Call the _INI function for each processor if present. This will be
done by ACPI-CA in the future.
* Fix a bug on SMP systems where CPUs will attach multiple times if the
bus is rescan.
* Document new sysctls for controlling idling.
- For acpi_pci_link_entry_dump(), add a few helper functions to display
the trigger mode, polarity, and sharemode of an individual IRQ resource.
These functions are then called for both regular and extended IRQ
resources.
- In acpi_pci_link_set_irq(), use the same type of IRQ resource
(regular vs. extended) for the new current resource as the type of
the resources from _PRS.
- When routing an interrupt don't ignore extended IRQ resources. Also,
use the same type of IRQ resource (regular vs. extended) for the new
current resource when as the type of the resource from _PRS.
