thorpej | Cleanup i2c bus acquire / release, centralizing all of the logic into
iic_acquire_bus() / iic_release_bus(). "acquire" and "release" hooks
no longer need to be provided by back-end controller drivers (only if
they need special handling, e.g. powering on the i2c controller).
This results in the removal of a bunch of rendundant code from each
back-end controller driver.
Assert that we are not in hard interrupt context in iic_acquire_bus(),
iic_exec(), and iic_release_bus().

Convert the entropy pool framework from pseudo-callout-driven to
soft interrupt driven operation.
Add a polling mode of operation -- now we can ask hardware random number
generators to top us up just when we need it (bcm2835_rng and amdpm
converted as examples).
Fix a stall noticed with repeated reads from /dev/random while testing.

Replace the xxx_acquire()/xxx_release() rwlocks with mutexes. There are
only RW_WRITERs for these, and no RW_READERs, so no need to incur the
extra overhead of allowing for both. As discussed on tech-kern.
For piixpm and ichsmb, the acquire/release protocol needs to be used,
even if the request is I2C_F_POLL'd (or if the device supports only
polled mode). Otherwise multiple requests can be running at the same
time, and they stomp on each other and create anomolous results.

First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>. This change includes
the following:
An initial cleanup and minor reorganization of the entropy pool
code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are
fixed. Some effort is made to accumulate entropy more quickly at
boot time.
A generic interface, "rndsink", is added, for stream generators to
request that they be re-keyed with good quality entropy from the pool
as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is
adjusted to use the rndsink interface for rekeying, which helps
address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random
number generator quality is provided (libkern/rngtest.c). This
is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is
based on an implementation of the NIST SP800-90 CTR_DRBG by
Henric Jungheim. This generator users AES in a modified counter
mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers
of randomness. The arc4random/arc4randbytes API is deprecated for
in-kernel use. It is replaced by "cprng_strong". The current
cprng_fast implementation wraps the existing arc4random
implementation. The current cprng_strong implementation wraps the
new CTR_DRBG implementation. Both interfaces are rekeyed from
the entropy pool automatically at intervals justifiable from best
current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as
the old arc4randbytes(), and cprng_strong() is about 20% faster
than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional
kernel component, as it is required by cprng_strong, which is
not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at
startup time; if it fails, the system will reboot. There is
approximately a 3/10000 chance of a false positive from these
tests. Entropy pool _input_ from hardware random numbers is
subjected to the rngtest tests at attach time, as well as the
FIPS continuous-output test, to detect bad or stuck hardware
RNGs; if any are detected, they are detached, but the system
continues to run.
A problem with rndctl(8) is fixed -- datastructures with
pointers in arrays are no longer passed to userspace (this
was not a security problem, but rather a major issue for
compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked
up to the new generators, but the /dev/*random pseudodevices
are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

Disgusting Xbox hack;
The "pci0 dev 1 function 2" aka "System Management" on the nForce chipset
isn't detected on the Xbox. If XBOX is defined and arch_i386_is_xbox is
true, force intrline to 12 and map the system management IO space at
0x8000. We can now call iic_smbus_intr when a system management interrupt
takes place.
While we're here, make amdpm_smbus honour the I2C_F_POLL flag.
The Xbox no longer resets when you press the eject button.

Add support for i2c bus on AMD-8111 used on many Opteron server motherboards,
and ADT 7463c thermal and voltage monitor found on the Tyan S2881 and S2882-D
(and probably other boards as well). We do not currently support any kind
of detection of the i2c address of the thermal monitor; it appears to be
at 0x2D on the S2881 and 0x2E on the S2882-D (kernel config examples
forthcoming).
