1ed2c0f5bc Remove DLINK_3, its unused. Remove NETGEAR FA410TX, since it is the
same as the LINKSYS COMBO_ECARD (which also seems to be the same as
another linksys product that also has a modem, but I can't find that
one at the moment).  Remove the PCM100, since it is now no longer
used.

6bf0e6ba56 o Remove duplicate LINKSYS ETHERFAST entry.
o The COMBO_ECARD comes in many flavors, it seems, so probe both the DL10019
  and the AX88x90 on it.  Since this seems to work with no ill effects, maybe
  the probing should happen more generally rather than being table driven.
  Need to think more about this.
o Remove PCM100 because it is duplicative (the ETHERFAST is the pcm100 and
  apparently has the same IDs).  It was here for NetBSD because they match
  up an expected MAC address OID, but since we don't bother with that, we
  don't need to be so finely discriminating.
o Minor style nit.

df89b62698 Next step on the road to IRPs: create and use an imitation of the
Windows DRIVER_OBJECT and DEVICE_OBJECT mechanism so that we can
simulate driver stacking.

In Windows, each loaded driver image is attached to a DRIVER_OBJECT
structure. Windows uses the registry to match up a given vendor/device
ID combination with a corresponding DRIVER_OBJECT. When a driver image
is first loaded, its DriverEntry() routine is invoked, which sets up
the AddDevice() function pointer in the DRIVER_OBJECT and creates
a dispatch table (based on IRP major codes). When a Windows bus driver
detects a new device, it creates a Physical Device Object (PDO) for
it. This is a DEVICE_OBJECT structure, with semantics analagous to
that of a device_t in FreeBSD. The Windows PNP manager will invoke
the driver's AddDevice() function and pass it pointers to the DRIVER_OBJECT
and the PDO.

The AddDevice() function then creates a new DRIVER_OBJECT structure of
its own. This is known as the Functional Device Object (FDO) and
corresponds roughly to a private softc instance. The driver uses
IoAttachDeviceToDeviceStack() to add this device object to the
driver stack for this PDO. Subsequent drivers (called filter drivers
in Windows-speak) can be loaded which add themselves to the stack.
When someone issues an IRP to a device, it travel along the stack
passing through several possible filter drivers until it reaches
the functional driver (which actually knows how to talk to the hardware)
at which point it will be completed. This is how Windows achieves
driver layering.

Project Evil now simulates most of this. if_ndis now has a modevent
handler which will use MOD_LOAD and MOD_UNLOAD events to drive the
creation and destruction of DRIVER_OBJECTs. (The load event also
does the relocation/dynalinking of the image.) We don't have a registry,
so the DRIVER_OBJECTS are stored in a linked list for now. Eventually,
the list entry will contain the vendor/device ID list extracted from
the .INF file. When ndis_probe() is called and detectes a supported
device, it will create a PDO for the device instance and attach it
to the DRIVER_OBJECT just as in Windows. ndis_attach() will then call
our NdisAddDevice() handler to create the FDO. The NDIS miniport block
is now a device extension hung off the FDO, just as it is in Windows.
The miniport characteristics table is now an extension hung off the
DRIVER_OBJECT as well (the characteristics are the same for all devices
handled by a given driver, so they don't need to be per-instance.)
We also do an IoAttachDeviceToDeviceStack() to put the FDO on the
stack for the PDO. There are a couple of fake bus drivers created
for the PCI and pccard buses. Eventually, there will be one for USB,
which will actually accept USB IRP.s

Things should still work just as before, only now we do things in
the proper order and maintain the correct framework to support passing
IRPs between drivers.

Various changes:

- corrected the comments about IRQL handling in subr_hal.c to more
  accurately reflect reality
- update ndiscvt to make the drv_data symbol in ndis_driver_data.h a
  global so that if_ndis_pci.o and/or if_ndis_pccard.o can see it.
- Obtain the softc pointer from the miniport block by referencing
  the PDO rather than a private pointer of our own (nmb_ifp is no
  longer used)
- implement IoAttachDeviceToDeviceStack(), IoDetachDevice(),
  IoGetAttachedDevice(), IoAllocateDriverObjectExtension(),
  IoGetDriverObjectExtension(), IoCreateDevice(), IoDeleteDevice(),
  IoAllocateIrp(), IoReuseIrp(), IoMakeAssociatedIrp(), IoFreeIrp(),
  IoInitializeIrp()
- fix a few mistakes in the driver_object and device_object definitions
- add a new module, kern_windrv.c, to handle the driver registration
  and relocation/dynalinkign duties (which don't really belong in
  kern_ndis.c).
- made ndis_block and ndis_chars in the ndis_softc stucture pointers
  and modified all references to it
- fixed NdisMRegisterMiniport() and NdisInitializeWrapper() so they
  work correctly with the new driver_object mechanism
- changed ndis_attach() to call NdisAddDevice() instead of ndis_load_driver()
  (which is now deprecated)
- used ExAllocatePoolWithTag()/ExFreePool() in lookaside list routines
  instead of kludged up alloc/free routines
- added kern_windrv.c to sys/modules/ndis/Makefile and files.i386.

7bb35cb182 Make it possible to unload ed. Move the ed_pccard_detach routine to

Since I don't actually have any non-pccard ed hardware I can test
with, I've only tested with my pccards.

More improvements in this area likely are possible.

29a3025dfa Fix crashdumps on twe. The twe_immediate_request() path was not only
copying data to a temporary buffer before the I/O, but also copying that
temporary buffer back to the original data location after the I/O.  When
you're dumping kernel heap and stack and protected pages, this is very
very bad.

d79055b325 ccs is a size_t. RAY_CCS_INDEX takes ccs and does math on it,
resulting in a size_t due to C's rules of arithmetic.  Rather than
bogusly cast the result to a uint8_t, fix the printf format specifier
to have a 'z' modifier which tells the compiler that the sizes really
do match.

It turns out that change 1.75 was incorrect to assume that this
'really' was a 8bit quantity.  It isn't.  Although the hardware
appears to limit things to < 256, it would be a bug that should be
caught by debug printf it it were.  Casting it to uint8_t would have
lost this useful information.

Aslo add 'z' to a nearby debug statement that's never compiled in.

5f0a1215d9 Notify the OS that we're taking over Px states in acpi_perf(4) instead of
doing it in the cpu driver.  The previous code was incorrect anyway since
this value controls Px states, not throttling as the comment said.  Since
we didn't support Px states before, there was no impact.  Also, note that
we delay the write to SMI_CMD until after booting is complete since it
sometimes triggers a change in the frequency and we want to have all
drivers ready to detect/handle this.
