f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

f246e4a17f - Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
  such abuse isn't really needed.  (And if we do need type information
  associated with a module then we should make it explicit and not
  use hacks.)

6cafe2646a Add support for MPI-350 the mini-pci Cisco Aironet card. This needs more
work.  The interface was gleaned from the Linux driver.  Currently only
one RX & one TX buffer are used.  Firmware support is not tested so for the
MPI-350 so it is disabled.  Signal cache and monitor mode are not supported
yet.  Signal cache is not supported since in encapsulation mode ethernet
frames are returned by the chip.  LAN monitor mode support will be added
shortly.  Thanks to Warner for the MPI-350 card he sent me.

Add support for RSSI map from PR kern/32880 which was incomplete.  Enhanced
with the ability to select the cache mode of raw, dbm or per-cent.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

0d6fcb5c0e Fix bugs in the structure for rx_frame by making gap length one byte and
a packed array so sizeof work.  This broke RFMON mode and passing
up 802.11 packets.

The Linux emulation code was derived from the open source Linux driver to
maintain compatibility.

LEAP support is added, hints from Richard Johnson.  I've verified this
locally with PC350v42510.img firmware.  More bug fixing from Marco to
fix long passwords.

Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep
so it doesn't look like your system died during a flash update.

Install header files in /usr/include/dev/an

Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol.
This way you can manage 2 keys a little easier.  Map the home mode into
key 5.  Enhance ifconfig to dump the various configured SSIDs.  I use
a bunch of different ones and roam between them.  Use the syntax similar
to the WEP keys to deal with setting difference SSIDs.

Bump up up the Card capabilities RID since they added 2 bytes to it
in the latest firmware.  Thankfully we changed it from a terminal
failure so the card still worked but the driver whined.

Some cleanup patches from Marco Molteni.

9ed346bab0 Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.
