e35d3a7828 - Remove g_gate_hold()/g_gate_release() from start/done paths. It saves
4 mutex operations per I/O requests.
- Use only one mutex to protect both (incoming and outgoing) queue.
  As MUTEX_PROFILING(9) shows, there is no big contention for this lock.
- Protect sc_queue_count with queue mutex, instead of doing atomic
  operations on it.
- Remove DROP_GIANT()/PICKUP_GIANT() - ggate is marked as MPSAFE and no
  Giant there.

887a166c34 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.

940e7b9e51 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.

79653046d8 Add a new sysctl, "security.jail.chflags_allowed", which controls the
behaviour of chflags within a jail.  If set to 0 (the default), then a
jailed root user is treated as an unprivileged user; if set to 1, then
a jailed root user is treated the same as an unjailed root user.

This is necessary to allow "make installworld" to work inside a jail,
since it attempts to manipulate the system immutable flag on certain
files.

dd19a799b8 Background writes are entirely an FFS/Softupdates thing.
Give FFS vnodes a specific bufwrite method which contains all the
background write stuff and then calls into the default bufwrite()
for the rest of the job.

Remove all the background write related stuff from the normal bufwrite.

This drags the softdep_move_dependencies() back into FFS.

Long term, it is worth looking at simply copying the data into
allocated memory and issuing the bio directly and not create the
"shadow buf" in the first place (just like copy-on-write is done
in snapshots for instance).  I don't think we really gain anything
but complexity from doing this with a buf.

e8ce55117b Use the local APIC timer to drive the various kernel clocks on SMP machines
rather than forwarding interrupts from the clock devices around using IPIs:
- Add an IDT vector that pushes a clock frame and calls
  lapic_handle_timer().
- Add functions to program the local APIC timer including setting the
  divisor, and setting up the timer to either down a periodic countdown
  or one-shot countdown.
- Add a lapic_setup_clock() function that the BSP calls from
  cpu_init_clocks() to setup the local APIC timer if it is going to be
  used.  The setup uses a one-shot countdown to calibrate the timer.  We
  then program the timer on each CPU to fire at a frequency of hz * 3.
  stathz is defined as freq / 23 (hz * 3 / 23), and profhz is defined as
  freq / 2 (hz * 3 / 2).  This gives the clocks relatively prime divisors
  while keeping a low LCM for the frequency of the clock interrupts.
  Thanks to Peter Jeremy for suggesting this approach.
- Remove the hardclock and statclock forwarding code including the two
  associated IPIs.  The bitmap IPI handler has now effectively degenerated
  to just IPI_AST.
- When the local APIC timer is used we don't turn the RTC on at all, but
  we still enable interrupts on the ISA timer 0 (i8254) for timecounting
  purposes.

b545a3b822 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.

Also, as long as we have not abandonned advanced vfs-stacking we

copy locally, use the VOP_LOCK_APV(&ufs) to correctly arrive at
vop_stdlock() at the bottom.
