87b4a25958 Add device driver support for the ASIX Electronics AX88172 USB 2.0
ethernet controller. The driver has been tested with the LinkSys
USB200M adapter. I know for a fact that there are other devices out
there with this chip but don't have all the USB vendor/device IDs.

Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.

e965edfda2 Add MAC_ALWAYS_LABEL_MBUF to options; this permits the administrator
to force the allocation of MAC labels for all mbufs regardless of
whether a configured policy requires labeling when the mbuf is
allocated.  This can be useful it you anticipate loading a fully
labeled policy after boot and don't want mbufs to exist without
label storage, for performance measurement purposes, etc.  It also
slightly lowers the overhead of m_tag labeling due to removing the
decision logic.

While here, improve commenting of other MAC options.

cc66ebe2a9 Commit a partial lazy thread switch mechanism for i386. it isn't as lazy
as it could be and can do with some more cleanup.  Currently its under
options LAZY_SWITCH.  What this does is avoid %cr3 reloads for short
context switches that do not involve another user process.  ie: we can
take an interrupt, switch to a kthread and return to the user without
explicitly flushing the tlb.  However, this isn't as exciting as it could
be, the interrupt overhead is still high and too much blocks on Giant
still.  There are some debug sysctls, for stats and for an on/off switch.

The main problem with doing this has been "what if the process that you're
running on exits while we're borrowing its address space?" - in this case
we use an IPI to give it a kick when we're about to reclaim the pmap.

Its not compiled in unless you add the LAZY_SWITCH option.  I want to fix a
few more things and get some more feedback before turning it on by default.

This is NOT a replacement for Bosko's lazy interrupt stuff.  This was more
meant for the kthread case, while his was for interrupts.  Mine helps a
little for interrupts, but his helps a lot more.

The stats are enabled with options SWTCH_OPTIM_STATS - this has been a
pseudo-option for years, I just added a bunch of stuff to it.

One non-trivial change was to select a new thread before calling
cpu_switch() in the first place.  This allows us to catch the silly
case of doing a cpu_switch() to the current process.  This happens
uncomfortably often.  This simplifies a bit of the asm code in cpu_switch
(no longer have to call choosethread() in the middle).  This has been
implemented on i386 and (thanks to jake) sparc64.  The others will come
soon.  This is actually seperate to the lazy switch stuff.

eae870cdb4 Add a new kernel option, MALLOC_MAKE_FAILURES, which compiles
in a debugging feature causing M_NOWAIT allocations to fail at
a specified rate.  This can be useful for detecting poor
handling of M_NOWAIT: the most frequent problems I've bumped
into are unconditional deference of the pointer even though
it's NULL, and hangs as a result of a lost event where memory
for the event couldn't be allocated.  Two sysctls are added:

debug.malloc.failure_rate

  How often to generate a failure: if set to 0 (default), this
  feature is disabled.  Otherwise, the frequency of failures --
  I've been using 10 (one in ten mallocs fails), but other
  popular settings might be much lower or much higher.

debug.malloc.failure_count

  Number of times a coerced malloc failure has occurred as a
  result of this feature.  Useful for tracking what might have
  happened and whether failures are being generated.

Useful possible additions: tying failure rate to malloc type,
printfs indicating the thread that experienced the coerced
failure.

halt any cpu in the idle loop now using machdep.hlt_cpus.

Examples of how to use this:

9d9edc5693 Add the MBUF_FRAG_TEST option. When compiled in, this option
allows you to tell ip_output to fragment all outgoing packets
into mbuf fragments of size net.inet.ip.mbuf_frag_size bytes.
This is an excellent way to test if network drivers can properly
handle long mbuf chains being passed to them.

net.inet.ip.mbuf_frag_size defaults to 0 (no fragmentation)
so that you can at least boot before your network driver dies. :)

00aabd830d - Remove unused cache flushing routines. These will not necessary work
on future UltraSPARC cpus for which the data cache is not direct mapped.
- Move UltraSPARC I and II (spitfire, blackbird, sapphire, sabre) specific
  functions to spitfire.c, and add cheetah.c for UltraSPARC III specific
  functions.  Initially just cache flushing, but there are a few other
  functions that will need to move here.
- Add an ipi handler for data cache flushing on UltraSPARC III.
- Use function pointers to select the right cache flushing functions based
  on cpu_impl.

With this it is possible to boot single user from an mfs root on UltraSPARC
III systems, including spinning up secondary processors.  There is currently
no support for the host to pci bridge, and no documentation for it is
publically available.

Thanks to Oleg Derevenetz for providing access to a system with UltraSPARC
III+ cpus.

ac7e2c0515 FIPS 140-2 rng data tester for h/w crypto devices. This driver periodically
monitors the entropy data harvested by crypto drivers to verify it complies
with FIPS 140-2.  If data fails any test then the driver discards it and
commences continuous testing of harvested data until it is deemed ok.
Results are collected in a statistics block and, optionally, reported on
the console.  In normal use the overhead associated with this driver is
not noticeable.

Note that drivers must (currently) be compiled specially to enable use.
