If _CID is string, it will need more complicated

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

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.

2a4689e84a Change ACPI make_dev() calls to use UID_ and GID_ constants rather
than hard-coded uids and gids.

Switch the device to a group of wheel instead of operator.

Narrow down the permissions on the device to require root privilege
to manipulate the system power state.  It may be that we can broaden
access to the device after review of the access control in ACPI.

I/O port range, then we should ignore a resource if it's NOT
a memory range AND NOT an I/O port range.
The OR in the condition caused us to ignore perfectly valid

9debb53220 According to the ACPI spec, the bus number of the child PCI bus of a host
to PCI bridge can be read be evaluating the _BBN method of the host to PCI
device.  Unfortunately, there appear to be some lazy/ignorant/moronic/
whatever BIOS writers that return 0 for _BBN for all host to PCI bridges in
the system.  On a system with a single host to PCI bridge this is not a
problem as the child bus of that single bridge will be bus 0 anyway.
However, on systems with multiple host to PCI bridges and l/i/m/w BIOS
writers this is a major problem resulting in all but the first host to
PCI bridge failing to attach.  So, this adds a workaround.

If the _BBN of a host to PCI bridge is zero and pcib0 already exists
and is not us, the we use _ADR to look up our PCI function and slot
(we currently assume we are on bus 0) and use that to call
host_pcib_get_busno() to try and extract our bus number from config
registers on the host to PCI bridge device.  If that fails, then we make
an evil assumption that ACPI's _SB_ namespace lays out the host to PCI
bridges in ascending order and use our pcib unit number as our bus
number.

21ac81ad19 Don't examine ACPI_STA_ENABLE bit of device's_STA object on initial
state.  Instead, use ACPI_STA_PRESENT and ACPI_STA_FUNCTIONAL for it.
In some ACPI BIOS implementations, boot disabled devices don't have
ACPI_STA_ENABLE bit in _STA object.
Also it is not fatal if getting current IRQ of boot disabled devices
is failed in initial state.

And minor fixes.

316ec49abd Some kernel threads try to do significant work, and the default KSTACK_PAGES
doesn't give them enough stack to do much before blowing away the pcb.
This adds MI and MD code to allow the allocation of an alternate kstack
who's size can be speficied when calling kthread_create.  Passing the
value 0 prevents the alternate kstack from being created.  Note that the
ia64 MD code is missing for now, and PowerPC was only partially written
due to the pmap.c being incomplete there.
Though this patch does not modify anything to make use of the alternate
kstack, acpi and usb are good candidates.

2ccfc93222 Overhaul the ACPI PCI bridge driver a bit:
- Add an ACPI PCI-PCI bridge driver (the previous driver just handled
  Host-PCI bridges) that is a PCI driver that is a subclass of the generic
  PCI-PCI bridge driver.  It overrides probe, attach, read_ivar, and
  pci_route_interrupt.
  - The probe routine only succeeds if our parent is an ACPI PCI bus which
    we test for by seeing if we can read our ACPI_HANDLE as an ivar.
  - The attach routine saves a copy of our handle and calls the new
    acpi_pcib_attach_common() function described below.
  - The read_ivar routine handles normal PCI-PCI bridge ivars and adds an
    ivar to return the ACPI_HANDLE of the bus this bridge represents.
  - The route_interrupt routine fetches the _PRT (PCI Interrupt Routing
    Table) from the bridge device's softc and passes it off to
    acpi_pcib_route_interrupt() to route the interrupt.
- Split the old ACPI Host-PCI bridge driver into two pieces.  Part of
  the attach routine and most of the route_interrupt routine remain in
  acpi_pcib.c and are shared by both ACPI PCI bridge drivers.
  - The attach routine verifies the PCI bridge is present, reads in
    the _PRT for the bridge, and attaches the child PCI bus.
  - The route_interrupt routine uses the passed in _PRT to route a PCI
    interrupt.
  The rest of the driver is the ACPI Host-PCI bridge specific bits that
  live in acpi_pcib_acpi.c.
  - We no longer duplicate pcib_maxslots but use it directly.
  - The driver now uses the pcib devclass instead of its own devclass.
    This means that PCI busses are now only children of pcib devices.
  - Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar
    of the child bus.
  - Fetch the _PRT for routing PCI interrupts directly from our softc
    instead of walking the devclass to find ourself and then fetch our
    own softc.

With this change and the new ACPI PCI bus driver, ACPI can now properly
route interrupts for devices behind PCI-PCI bridges.  That is, the
Itanium2 with like 10 PCI busses can now boot ok and route all the PCI
interrupts.  Hopefully this will also fix problems people are having with
CardBus bridges behind PCI-PCI bridges not properly routing interrupts
when ACPI is used.
