dc08ffec87 Device megapatch 4/6:
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

70be398070 It appears that the changes in the resources allocated is causing much
pain and suffering.  Attempt to back it out by removing the 'if the
requested range is larger than the window, clip to the window' code.
This is a band-aide until the issues are better understood and the
issues with the lazy allocation patches are resolved.

e4b59fc500 Add support for subtractive decoding bridges. These bridges pass all
signals to addresses to the child busses.  Typically, ProgIf of 1
means a subtractive bridge.  However, Intel has a whole lot of ones
with a ProgIf of 80 that are also subtractive.  We cope with these
bridges too.  This eliminates hw.pci.allow_unsupported_io_range
because that had almost the same effect as these patches (almost means
'buggy').  Remove the bogus checks for ISA bus locations: these cycles
aren't special and are only passed by transparent bridges.

We allow any range to succeed.  If the range is a superset of the
range that's decoded, trim the resource to that range.  Otherwise,
pass the range unchanged.  This will change the location that PC Card
and CardBus cards are attached.  This might bogusly cause some
overlapping allocation that wasn't present before, but the overlapping
fixes need to be in the pci level.

There's also a few formatting changes here.

0d2a298904 Initial landing of SMP support for FreeBSD/amd64.
- This is heavily derived from John Baldwin's apic/pci cleanup on i386.
- I have completely rewritten or drastically cleaned up some other parts.
  (in particular, bootstrap)
- This is still a WIP.  It seems that there are some highly bogus bioses
  on nVidia nForce3-150 boards.  I can't stress how broken these boards
  are.  I have a workaround in mind, but right now the Asus SK8N is broken.
  The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed.
- Most of my testing has been with SCHED_ULE.  SCHED_4BSD works.
- the apic and acpi components are 'standard'.
- If you have an nVidia nForce3-150 board, you are stuck with 'device
  atpic' in addition, because they somehow managed to forget to connect the
  8254 timer to the apic, even though its in the same silicon!  ARGH!
  This directly violates the ACPI spec.

66f314b5f2 The code that was meant to test alignment of the register offset
parameter in the read and write case dereferenced an unitialized
pointer and can't possibly ever have catched an actual invalid
argument.

This was apparently true for the read/write and getconf cases. The
latter does not even receive the paramter that is to be verified.

I'm surprised that this did not cause kernel panics, but it seems
that the uninitialized local variable happens to contain data that
may be used as a pointer to memory that satisfies the test condition.

Make the code work as intended by moving the test inside the switch
case where the pointer has been properly initialized.

Since the read and write case shared just about all code (except
for the single call to PCIB_READ_CONFIG resp. PCIB_WRITE_CONFIG) I
have merged both cases.

3920999db7 Add a new PCI interface method, assign_interrupt, to determine the
interrupt to be used for a device. This is intended solely for internal
use of PCI bus implementations, and exists so that PCI bus drivers
implementing special interrupt assignment methods which require
additional work at the bus level to work right can be easily derived
from the generic driver (or any other one) without resorting to hacks.

It will be used in the sparc64 ofw_pcibus driver, which will be
committed shortly.

Make use of this method in the generic implementation, and add it to
the method table of bus drivers derived from the PCI one.

036c2cfbfa Allow to write the intpin ivar using the pci_set_intpin() accessor. There
are some Sun PCI devices around which bogusly set intpin to 0, although
they use the intline mechanism; this allows the device driver to correct
that.

1beb381637 - Adjust the comment about re-routing PCI interrupts to be less
ia64-specific.
- When trying to re-route interrupts, don't change cfg->intline if the
  re-route fails by returning an invalid vector.  This fixes machines
  without any way of routing interrupts such as older PC's without a
  $PIR table.

We do not currently write the new intline value back to the hardware, but
we should.  That will likely be added in a later commit.

because these bits should have been set earlier in the process.  In
