099894cc96 Declare the sbus(4) front-end of puc(4) also for fhc(4), allowing
uart(4) to support the Zilog 8530 SCCs which hang off of a FireHose
bus on Sun E4000/E5000 class machines.
Beside the fact that a puc_fhc.c would just be a copy of puc_sbus.c
with s,sbus,fhc,g the reason why the declaration for fhc(4) was
sticked into puc_sbus.c is that both of these front-ends for puc(4)
will go away once there is a scc(4).

63ba67b69c - Correct one aspect of the driver_object/device_object/IRP framework:
when we create a PDO, the driver_object associated with it is that
  of the parent driver, not the driver we're trying to attach. For
  example, if we attach a PCI device, the PDO we pass to the NdisAddDevice()
  function should contain a pointer to fake_pci_driver, not to the NDIS
  driver itself. For PCI or PCMCIA devices this doesn't matter because
  the child never needs to talk to the parent bus driver, but for USB,
  the child needs to be able to send IRPs to the parent USB bus driver, and
  for that to work the parent USB bus driver has to be hung off the PDO.

  This involves modifying windrv_lookup() so that we can search for
  bus drivers by name, if necessary. Our fake bus drivers attach themselves
  as "PCI Bus," "PCCARD Bus" and "USB Bus," so we can search for them
  using those names.

  The individual attachment stubs now create and attach PDOs to the
  parent bus drivers instead of hanging them off the NDIS driver's
  object, and in if_ndis.c, we now search for the correct driver
  object depending on the bus type, and use that to find the correct PDO.

  With this fix, I can get my sample USB ethernet driver to deliver
  an IRP to my fake parent USB bus driver's dispatch routines.

- Add stub modules for USB support: subr_usbd.c, usbd_var.h and
  if_ndis_usb.c. The subr_usbd.c module is hooked up the build
  but currently doesn't do very much. It provides the stub USB
  parent driver object and a dispatch routine for
  IRM_MJ_INTERNAL_DEVICE_CONTROL. The only exported function at
  the moment is USBD_GetUSBDIVersion(). The if_ndis_usb.c stub
  compiles, but is not hooked up to the build yet. I'm putting
  these here so I can keep them under source code control as I
  flesh them out.

099dd0430b Bring back the full packet destination manipulation for 'ipfw fwd'
with the kernel compile time option:

 options IPFIREWALL_FORWARD_EXTENDED

This option has to be specified in addition to IPFIRWALL_FORWARD.

With this option even packets targeted for an IP address local
to the host can be redirected.  All restrictions to ensure proper
behaviour for locally generated packets are turned off.  Firewall
rules have to be carefully crafted to make sure that things like
PMTU discovery do not break.

Document the two kernel options.

d8f2dda739 Add support for Windows/x86-64 binaries to Project Evil.
Ville-Pertti Keinonen (will at exomi dot comohmygodnospampleasekthx)
deserves a big thanks for submitting initial patches to make it
work. I have mangled his contributions appropriately.

The main gotcha with Windows/x86-64 is that Microsoft uses a different
calling convention than everyone else. The standard ABI requires using
6 registers for argument passing, with other arguments on the stack.
Microsoft uses only 4 registers, and requires the caller to leave room
on the stack for the register arguments incase the callee needs to
spill them. Unlike x86, where Microsoft uses a mix of _cdecl, _stdcall
and _fastcall, all routines on Windows/x86-64 uses the same convention.
This unfortunately means that all the functions we export to the
driver require an intermediate translation wrapper. Similarly, we have
to wrap all calls back into the driver binary itself.

The original patches provided macros to wrap every single routine at
compile time, providing a secondary jump table with a customized
wrapper for each exported routine. I decided to use a different approach:
the call wrapper for each function is created from a template at
runtime, and the routine to jump to is patched into the wrapper as
it is created. The subr_pe module has been modified to patch in the
wrapped function instead of the original. (On x86, the wrapping
routine is a no-op.)

There are some minor API differences that had to be accounted for:

- KeAcquireSpinLock() is a real function on amd64, not a macro wrapper
  around KfAcquireSpinLock()
- NdisFreeBuffer() is actually IoFreeMdl(). I had to change the whole
  NDIS_BUFFER API a bit to accomodate this.

Bugs fixed along the way:
- IoAllocateMdl() always returned NULL
- kern_windrv.c:windrv_unload() wasn't releasing private driver object
  extensions correctly (found thanks to memguard)

This has only been tested with the driver for the Broadcom 802.11g
chipset, which was the only Windows/x86-64 driver I could find.

969eaf2179 Break out obscure ISA cards into their own files, as well as ne2000
and wd80x3 support.  Make the obscure ISA cards optional, and add
those options to NOTES on i386 (note: the ifdef around the whole code
is for module building).  Tweak pc98 ed support to include wd80x3 too.
Add goo for alpha too.

The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that
is).  I couldn't find any of these for sale on ebay, so they are
untested.  If you have one of these cards, and send it to me, I'll
ensure that you have no future problems with it...

Minor cleanups as well by using functions rather than cut and paste
code for some probing operations (where the function call overhead is
lost in the noise).

Remove use of kvtop, since they aren't required anymore.  This driver
needs to get its memory mapped act together, however, and use bus
space.  It doesn't right now.

This reduces the size of if_ed.ko from about 51k to 33k on my laptop.

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.

This means that you can capture print/plot like output from your

	cat -u /dev/gpib0l > /tmp/somefile

Since there is no way to know when no more output is comming you
will have to ctrl-C the cat process when it is done (that is why
the -u is important).

e4eb384b47 Bring in MemGuard, a very simple and small replacement allocator
designed to help detect tamper-after-free scenarios, a problem more
and more common and likely with multithreaded kernels where race
conditions are more prevalent.

Currently MemGuard can only take over malloc()/realloc()/free() for
particular (a) malloc type(s) and the code brought in with this
change manually instruments it to take over M_SUBPROC allocations
as an example.  If you are planning to use it, for now you must:

	1) Put "options DEBUG_MEMGUARD" in your kernel config.
	2) Edit src/sys/kern/kern_malloc.c manually, look for
	   "XXX CHANGEME" and replace the M_SUBPROC comparison with
	   the appropriate malloc type (this might require additional
	   but small/simple code modification if, say, the malloc type
	   is declared out of scope).
	3) Build and install your kernel.  Tune vm.memguard_divisor
	   boot-time tunable which is used to scale how much of kmem_map
	   you want to allott for MemGuard's use.  The default is 10,
	   so kmem_size/10.

ToDo:
	1) Bring in a memguard(9) man page.
	2) Better instrumentation (e.g., boot-time) of MemGuard taking
	   over malloc types.
	3) Teach UMA about MemGuard to allow MemGuard to override zone
	   allocations too.
	4) Improve MemGuard if necessary.

This work is partly based on some old patches from Ian Dowse.

6c5c0a5ac1 Separate mse driver into a core driver and a bus attachments. Separate out
the ISA and CBUS (called isa on pc98) attachments.  Eliminate all PC98
ifdefs in the process (the driver in pc98/pc98/mse.c was a copy of the one
in i386/isa/mse.c with PC98 ifdefs).  Create a module for this driver.

I've tested this my PC-9821RaS40 with moused.  I've not tested this on i386
because I have no InPort cards, or similar such things.  NEC standardized
on bus mice very early, long before ps/2 mice ports apeared, so all PC-98
machines supported by FreeBSD/pc98 have bus mice, I believe.

aec0fb7b40 Back when VOP_* was introduced, we did not have new-style struct
initializations but we did have lofty goals and big ideals.

Adjust to more contemporary circumstances and gain type checking.

	Replace the entire vop_t frobbing thing with properly typed
	structures.  The only casualty is that we can not add a new
	VOP_ method with a loadable module.  History has not given
	us reason to belive this would ever be feasible in the the
	first place.

	Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc.

	Give coda correct prototypes and function definitions for
	all vop_()s.

	Generate a bit more data from the vnode_if.src file:  a
	struct vop_vector and protype typedefs for all vop methods.

	Add a new vop_bypass() and make vop_default be a pointer
	to another struct vop_vector.

	Remove a lot of vfs_init since vop_vector is ready to use
	from the compiler.

	Cast various vop_mumble() to void * with uppercase name,
	for instance VOP_PANIC, VOP_NULL etc.

	Implement VCALL() by making vdesc_offset the offsetof() the
	relevant function pointer in vop_vector.  This is disgusting
	but since the code is generated by a script comparatively
	safe.  The alternative for nullfs etc. would be much worse.

	Fix up all vnode method vectors to remove casts so they
	become typesafe.  (The bulk of this is generated by scripts)

on UltraSPARC workstations. The driver is based on OpenBSD's SBus
cs4231 driver and heavily modified to incorporate into sound(4)
infrastructure. Due to the lack of APCDMA documentation, the DMA
code of SBus cs4231 came from OpenBSD's driver.
The driver runs without Giant lock and supports both SBus and EBus
based CS4231 audio controller. Special thanks to marius for providing
feedbacks during the driver writing. His feedback made it possible
to write hiccup free playback code under high system loads.

e47bf36158 Back out v1.49. Recent findings suggest sparc64 may not be ready for
-O2 on kernel compiles after all.  While working on adding a KASSERT
to sparc64/sparc64/rwindow.c I found that it was "position sensitive",
putting it above a call to flushw() instead of below caused corruption
of processes on the system.  jake and jhb have both confirmed there is
no obvious explanation for that.  The exact same kernel code does not
have the process corruption problem if compiled with -O instead of -O2.
There have been signs of similar issues floated on the sparc64@ mailing
list, lets see if this helps make them go away.

Note this isn't an optimal fix as far as the file format goes, if this
disgusts too many people I'll fix it the right way.  Since compiling
with something other than -O is a known problem this format would prevent
a change to the default causing grief.  And this may also help motivate
finding out what the compiler is doing wrong so we can shift back to
using -O2. :-)

malloc is called M_WAITOK but no locking is provided (yet).  A bit of

a "caller provides locking" strategy can be maintained, but that may
require use of M_NOWAIT allocation and failure handling.

8985c52bb6 Device driver for the Cypress CY7C637xx and CY7C640/1xx families of USB
to RS232 bridges, such as the one found in the DeLorme Earthmate USB GPS
receiver (which is the only device currently supported by this driver).

While other USB to serial drivers in the tree rely heavily on ucom, this
one is self-contained.  The reason for that is that ucom assumes that
the bridge uses bulk pipes for I/O, while the Cypress parts actually
register as human interface devices and use HID reports for configuration
and I/O.

The driver is not entirely complete: there is no support yet for flow
control, and output doesn't seem to work, though I don't know if that is
because of a bug in the code, or simply because the Earthmate is a read-
only device.

ed062c8d66 Refactor a bunch of scheduler code to give basically the same behaviour
but with slightly cleaned up interfaces.

The KSE structure has become the same as the "per thread scheduler
private data" structure. In order to not make the diffs too great
one is #defined as the other at this time.

The KSE (or td_sched) structure is  now allocated per thread and has no
allocation code of its own.

Concurrency for a KSEGRP is now kept track of via a simple pair of counters
rather than using KSE structures as tokens.

Since the KSE structure is different in each scheduler, kern_switch.c
is now included at the end of each scheduler. Nothing outside the
scheduler knows the contents of the KSE (aka td_sched) structure.

The fields in the ksegrp structure that are to do with the scheduler's
queueing mechanisms are now moved to the kg_sched structure.
(per ksegrp scheduler private data structure). In other words how the
scheduler queues and keeps track of threads is no-one's business except
the scheduler's. This should allow people to write experimental
schedulers with completely different internal structuring.

A scheduler call sched_set_concurrency(kg, N) has been added that
notifies teh scheduler that no more than N threads from that ksegrp
should be allowed to be on concurrently scheduled. This is also
used to enforce 'fainess' at this time so that a ksegrp with
10000 threads can not swamp a the run queue and force out a process
with 1 thread, since the current code will not set the concurrency above
NCPU, and both schedulers will not allow more than that many
onto the system run queue at a time. Each scheduler should eventualy develop
their own methods to do this now that they are effectively separated.

Rejig libthr's kernel interface to follow the same code paths as
linkse for scope system threads. This has slightly hurt libthr's performance
but I will work to recover as much of it as I can.

Thread exit code has been cleaned up greatly.
exit and exec code now transitions a process back to
'standard non-threaded mode' before taking the next step.

1d8cd39e71 Change the default disposition of debug.mpsafenet from 0 to 1, which
will cause the network stack to operate without the Giant lock by
default.  This change has the potential to improve performance by
increasing parallelism and decreasing latency in network processing.

Due to the potential exposure of existing or new bugs, the following
compatibility functionality is maintained:

- It is still possible to disable Giant-free operation by setting
  debug.mpsafenet to 0 in loader.conf.

- Add "options NET_WITH_GIANT", which will restore the default value of
  debug.mpsafenet to 0, and is intended for use on systems compiled with
  known unsafe components, or where a more conservative configuration is
  desired.

- Add a new declaration, NET_NEEDS_GIANT("componentname"), which permits
  kernel components to declare dependence on Giant over the network
  stack.  If the declaration is made by a preloaded module or a compiled
  in component, the disposition of debug.mpsafenet will be set to 0 and
  a warning concerning performance degraded operation printed to the
  console.  If it is declared by a loadable kernel module after boot, a
  warning is displayed but the disposition cannot be changed.  This is
  implemented by defining a new SYSINIT() value, SI_SUB_SETTINGS, which
  is intended for the processing of configuration choices after tunables
  are read in and the console is available to generate errors, but
  before much else gets going.

This compatibility behavior will go away when we've finished the last
of the locking work and are confident that operation is correct.

9b932e9e04 Convert ipfw to use PFIL_HOOKS. This is change is transparent to userland
and preserves the ipfw ABI.  The ipfw core packet inspection and filtering
functions have not been changed, only how ipfw is invoked is different.

However there are many changes how ipfw is and its add-on's are handled:

 In general ipfw is now called through the PFIL_HOOKS and most associated
 magic, that was in ip_input() or ip_output() previously, is now done in
 ipfw_check_[in|out]() in the ipfw PFIL handler.

 IPDIVERT is entirely handled within the ipfw PFIL handlers.  A packet to
 be diverted is checked if it is fragmented, if yes, ip_reass() gets in for
 reassembly.  If not, or all fragments arrived and the packet is complete,
 divert_packet is called directly.  For 'tee' no reassembly attempt is made
 and a copy of the packet is sent to the divert socket unmodified.  The
 original packet continues its way through ip_input/output().

 ipfw 'forward' is done via m_tag's.  The ipfw PFIL handlers tag the packet
 with the new destination sockaddr_in.  A check if the new destination is a
 local IP address is made and the m_flags are set appropriately.  ip_input()
 and ip_output() have some more work to do here.  For ip_input() the m_flags
 are checked and a packet for us is directly sent to the 'ours' section for
 further processing.  Destination changes on the input path are only tagged
 and the 'srcrt' flag to ip_forward() is set to disable destination checks
 and ICMP replies at this stage.  The tag is going to be handled on output.
 ip_output() again checks for m_flags and the 'ours' tag.  If found, the
 packet will be dropped back to the IP netisr where it is going to be picked
 up by ip_input() again and the directly sent to the 'ours' section.  When
 only the destination changes, the route's 'dst' is overwritten with the
 new destination from the forward m_tag.  Then it jumps back at the route
 lookup again and skips the firewall check because it has been marked with
 M_SKIP_FIREWALL.  ipfw 'forward' has to be compiled into the kernel with
 'option IPFIREWALL_FORWARD' to enable it.

 DUMMYNET is entirely handled within the ipfw PFIL handlers.  A packet for
 a dummynet pipe or queue is directly sent to dummynet_io().  Dummynet will
 then inject it back into ip_input/ip_output() after it has served its time.
 Dummynet packets are tagged and will continue from the next rule when they
 hit the ipfw PFIL handlers again after re-injection.

 BRIDGING and IPFW_ETHER are not changed yet and use ipfw_chk() directly as
 they did before.  Later this will be changed to dedicated ETHER PFIL_HOOKS.

More detailed changes to the code:

 conf/files
	Add netinet/ip_fw_pfil.c.

 conf/options
	Add IPFIREWALL_FORWARD option.

 modules/ipfw/Makefile
	Add ip_fw_pfil.c.

 net/bridge.c
	Disable PFIL_HOOKS if ipfw for bridging is active.  Bridging ipfw
	is still directly invoked to handle layer2 headers and packets would
	get a double ipfw when run through PFIL_HOOKS as well.

 netinet/ip_divert.c
	Removed divert_clone() function.  It is no longer used.

 netinet/ip_dummynet.[ch]
	Neither the route 'ro' nor the destination 'dst' need to be stored
	while in dummynet transit.  Structure members and associated macros
	are removed.

 netinet/ip_fastfwd.c
	Removed all direct ipfw handling code and replace it with the new
	'ipfw forward' handling code.

 netinet/ip_fw.h
	Removed 'ro' and 'dst' from struct ip_fw_args.

 netinet/ip_fw2.c
	(Re)moved some global variables and the module handling.

 netinet/ip_fw_pfil.c
	New file containing the ipfw PFIL handlers and module initialization.

 netinet/ip_input.c
	Removed all direct ipfw handling code and replace it with the new
	'ipfw forward' handling code.  ip_forward() does not longer require
	the 'next_hop' struct sockaddr_in argument.  Disable early checks
	if 'srcrt' is set.

 netinet/ip_output.c
	Removed all direct ipfw handling code and replace it with the new
	'ipfw forward' handling code.

 netinet/ip_var.h
	Add ip_reass() as general function.  (Used from ipfw PFIL handlers
	for IPDIVERT.)

 netinet/raw_ip.c
	Directly check if ipfw and dummynet control pointers are active.

 netinet/tcp_input.c
	Rework the 'ipfw forward' to local code to work with the new way of
	forward tags.

 netinet/tcp_sack.c
	Remove include 'opt_ipfw.h' which is not needed here.

 sys/mbuf.h
	Remove m_claim_next() macro which was exclusively for ipfw 'forward'
	and is no longer needed.

a632deec30 Add an "options MP_WATCHDOG" to i386. This option allows one of the
logical CPUs on a system to be used as a dedicated watchdog to cause a
drop to the debugger and/or generate an NMI to the boot processor if
the kernel ceases to respond.  A sysctl enables the watchdog running
out of the processor's idle thread; a callout is launched to reset a
timer in the watchdog.  If the callout fails to reset the timer for ten
seconds, the watchdog will fire.  The sysctl allows you to select which
CPU will run the watchdog.

A sample "debug.leak_schedlock" is included, which causes a sysctl to
spin holding sched_lock in order to trigger the watchdog.  On my Xeons,
the watchdog is able to detect this failure mode and break into the
debugger, which cannot otherwise be done without an NMI button.

This option does not currently work with sched_ule due to ule's push
notion of scheduling, similar to machdep.hlt_logical_cpus failing to
work with that scheduler.

On face value, this might seem somewhat inefficient, but there are a
lot of dual-processor Xeons with HTT around, so using one as a watchdog
for testing is not as inefficient as one might fear.

1f44b0a1b5 Get rid of the RANDOM_IP_ID option and make it a sysctl. NetBSD
have already done this, so I have styled the patch on their work:

        1) introduce a ip_newid() static inline function that checks
        the sysctl and then decides if it should return a sequential
        or random IP ID.

        2) named the sysctl net.inet.ip.random_id

        3) IPv6 flow IDs and fragment IDs are now always random.
        Flow IDs and frag IDs are significantly less common in the
        IPv6 world (ie. rarely generated per-packet), so there should
        be smaller performance concerns.

The sysctl defaults to 0 (sequential IP IDs).

26280d88d7 - Introduce an ofw_bus kobj-interface for retrieving the OFW node and a
subset ("compatible", "device_type", "model" and "name") of the standard
  properties in drivers for devices on Open Firmware supported busses. The
  standard properties "reg", "interrupts" und "address" are not covered by
  this interface because they are only of interest in the respective bridge
  code. There's a remaining standard property "status" which is unclear how
  to support properly but which also isn't used in FreeBSD at present.
  This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
  ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
  vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
  This in turn allows to simplify and remove code-duplication in drivers for
  devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
  drivers for their children to use the ofw_bus kobj-interface. The IVAR-
  interfaces of the Central, EBus and FHC are entirely replaced by this. The
  PCI bus driver used its own kobj-interface and now also uses the ofw_bus
  one. The IVARs special to the SBus, e.g. for retrieving the burst size,
  remain.
  Beware: this causes an ABI-breakage for modules of drivers which used the
  IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
  recompiled.
  The style-inconsistencies introduced in some of the bus drivers will be
  fixed by tmm@ in a generic clean-up of the respective drivers later (he
  requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
  use the ofw_bus kobj-interface. This invloves removing the IVARs related
  to the "reg" property which were unused and a leftover from the NetBSD
  origini of the code. There's no ABI-breakage caused by this because none
  of these driver are currently built as modules.
  There are other powerpc bus drivers which can be converted to the ofw_bus
  kobj-interface, e.g. the PCI bus driver, which should be done together
  with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
  advantage of the ofw_bus kobj-interface and simplify them a bit.

8ab2f5ecc5 Break out the MI part of the /dev/[k]mem and /dev/io drivers into
their own directory and module, leaving the MD parts in the MD
area (the MD parts _are_ part of the modules). /dev/mem and /dev/io
are now loadable modules, thus taking us one step further towards
a kernel created entirely out of modules. Of course, there is nothing
preventing the kernel from having these statically compiled.

a9abdce44a Add "options ADAPTIVE_GIANT" which causes Giant to also be treated in
an adaptive fashion when adaptive mutexes are enabled.  The theory
behind non-adaptive Giant is that Giant will be held for long periods
of time, and therefore spinning waiting on it is wasteful.  However,
in MySQL benchmarks which are relatively Giant-free, running Giant
adaptive makes an observable difference on SMP (5% transaction rate
improvement).  As such, make adaptive behavior on Giant an option so
it can be more widely benchmarked.

quite some time, and has been extensively tested on i386 and sparc64.  It
shows measurable performance gains in many circumstances, and few negative
effects.  It would be nice in t he future if adaptive mutexes actually went
to sleep after a certain amount of spinning, but that will require quite a
bit more testing.

e2ee21738f Update for the KDB framework:
o  Rename WITNESS_DDB to WITNESS_KDB. In the new world order KDB is the
   acronym to use for debugging related code. The DDB option is used
   to enable the DDB debugger backend only.
o  Likewise, rename DDB_TRACE to KDB_TRACE, rename DDB_UNATTENDED to
   KDB_UNATTENDED and rename SC_HISTORY_DDBKEY to SC_HISTORY_KDBKEY.
o  Remove DDB_NOKLDSYM. The new DDB backend supports pre-linker symbol
   lookups as well as KLD symbol lookups at the same time.
o  Remove GDB_REMOTE_CHAT. The GDB protocol hacks to allow this are
   FreeBSD specific. At the same time, the GDB protocol has packets
   for console output.

37224cd3fc Mega update for the KDB framework: turn DDB into a KDB backend.
Most of the changes are a direct result of adding thread awareness.
Typically, DDB_REGS is gone. All registers are taken from the
trapframe and backtraces use the PCB based contexts. DDB_REGS was
defined to be a trapframe on all platforms anyway.
Thread awareness introduces the following new commands:
	thread X	switch to thread X (where X is the TID),
	show threads	list all threads.

The backtrace code has been made more flexible so that one can
create backtraces for any thread by giving the thread ID as an
argument to trace.

With this change, ia64 has support for breakpoints.

6af8e47df7 Update for the KDB framework. Sanitize the alpha console code now that
it's in the way even more. Basicly: remove all alpha specific console
support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console
initialization to be identical to all other platforms. In a nutshell:
call cninit().
The platform specific code now only sets or clears RB_SERIAL and thus
automaticly causes the right console to be selected.

sio.c:
o  Replace the remote GDB hacks and use the GDB debug port interface
   instead.
o  Make debugging code conditional upon KDB instead of DDB.
o  Call kdb_alt_break() instead of db_alt_break().
o  Call kdb_enter() instead of breakpoint().
o  Remove the ugly compatibility of using the console as the debug
   port.

8ade021a7c Break out the isa and pccard front ends to the fdc controller device.
This should allow us to more easily break out the acpi and 'legacy pc'
front ends as well (so only the bus front end would touch rtc, for
example).

This isn't a great separation, since isa dma routines are still called
from the MI code, but it is a start.

3bc482ec1c By popular request, add a workaround that allows large (>128GB or so)
FAT32 filesystems to be mounted, subject to some fairly serious limitations.

This works by extending the internal pseudo-inode-numbers generated from
the file's starting cluster number to 64-bits, then creating a table
mapping these into arbitrary 32-bit inode numbers, which can fit in
struct dirent's d_fileno and struct vattr's va_fileid fields. The mappings
do not persist across unmounts or reboots, so it's not possible to export
these filesystems through NFS. The mapping table may grow to be rather
large, and may grow large enough to exhaust kernel memory on filesystems
with millions of files.

Don't enable this option unless you understand the consequences.

0c0b25ae91 Implement preemption of kernel threads natively in the scheduler rather
than as one-off hacks in various other parts of the kernel:
- Add a function maybe_preempt() that is called from sched_add() to
  determine if a thread about to be added to a run queue should be
  preempted to directly.  If it is not safe to preempt or if the new
  thread does not have a high enough priority, then the function returns
  false and sched_add() adds the thread to the run queue.  If the thread
  should be preempted to but the current thread is in a nested critical
  section, then the flag TDF_OWEPREEMPT is set and the thread is added
  to the run queue.  Otherwise, mi_switch() is called immediately and the
  thread is never added to the run queue since it is switch to directly.
  When exiting an outermost critical section, if TDF_OWEPREEMPT is set,
  then clear it and call mi_switch() to perform the deferred preemption.
- Remove explicit preemption from ithread_schedule() as calling
  setrunqueue() now does all the correct work.  This also removes the
  do_switch argument from ithread_schedule().
- Do not use the manual preemption code in mtx_unlock if the architecture
  supports native preemption.
- Don't call mi_switch() in a loop during shutdown to give ithreads a
  chance to run if the architecture supports native preemption since
  the ithreads will just preempt DELAY().
- Don't call mi_switch() from the page zeroing idle thread for
  architectures that support native preemption as it is unnecessary.
- Native preemption is enabled on the same archs that supported ithread
  preemption, namely alpha, i386, and amd64.

This change should largely be a NOP for the default case as committed
except that we will do fewer context switches in a few cases and will
avoid the run queues completely when preempting.

e1237b285b Introduce GEOM_LABEL class.
This class is used for detecting volume labels on file systems:
UFS, MSDOSFS (FAT12, FAT16, FAT32) and ISO9660.
It also provide native labelization (there is no need for file system).

g_label_ufs.c is based on geom_vol_ffs from Gordon Tetlow.
g_label_msdos.c and g_label_iso9660.c are probably hacks, I just found
where volume labels are stored and I use those offsets here,
but with this class it should be easy to do it as it should be done by
someone who know how.
Implementing volume labels detection for other file systems also should
be trivial.

New providers are created in those directories:
/dev/ufs/ (UFS1, UFS2)
/dev/msdosfs/ (FAT12, FAT16, FAT32)
/dev/iso9660/ (ISO9660)
/dev/label/ (native labels, configured with glabel(8))

Manual page cleanups and some comments inside were submitted by
Simon L. Nielsen, who was, as always, very helpful. Thanks!
