6810ad6f2a Overhaul driver/subsystem api's:
o make all crypto drivers have a device_t; pseudo drivers like the s/w
  crypto driver synthesize one
o change the api between the crypto subsystem and drivers to use kobj;
  cryptodev_if.m defines this api
o use the fact that all crypto drivers now have a device_t to add support
  for specifying which of several potential devices to use when doing
  crypto operations
o add new ioctls that allow user apps to select a specific crypto device
  to use (previous ioctls maintained for compatibility)
o overhaul crypto subsystem code to eliminate lots of cruft and hide
  implementation details from drivers
o bring in numerous fixes from Michale Richardson/hifn; mostly for
  795x parts
o add an optional mechanism for mmap'ing the hifn 795x public key h/w
  to user space for use by openssl (not enabled by default)
o update crypto test tools to use new ioctl's and add cmd line options
  to specify a device to use for tests

These changes will also enable much future work on improving the core
crypto subsystem; including proper load balancing and interposing code
between the core and drivers to dispatch small operations to the s/w
driver as appropriate.

These changes were instigated by the work of Michael Richardson.

b623eec509 Avoid memory allocations when the given address is already 16 bytes aligned.
Such an address can be used directly in padlock's AES.
This improves speed of geli(8) significantly:

	# sysctl kern.geom.zero.clear=0
	# geli onetime -s 4096 gzero
	# dd if=/dev/gzero.eli of=/dev/null bs=1m count=1000

5333bd4763 Implement support for HMAC/SHA1 and HMAC/SHA256 acceleration found in
new VIA CPUs.
For older CPUs HMAC/SHA1 and HMAC/SHA256 (and others) will still be done
in software.

Move symmetric cryptography (currently only AES-CBC 128/192/256) to
padlock_cipher.c file. Move HMAC cryptography to padlock_hash.c file.

5362e27b6d Set ses_ictx and ses_octx to NULL after freeing them, so we won't free
them twice.
This is possible for example in situation when session is used in
authentication context, then freed and then used in encryption context
and freed - in encryption context ses_ictx and ses_octx are not touched
at newsession time, but padlock_freesession could still try to free them
when they are not NULL.

64e18040cc - Pretend to accelerate various HMAC algorithms, so padlock(4) can be used
with fast_ipsec(4) and geli(8) authentication (comming soon).
  If consumer requests only for HMAC algorithm (without encryption), return
  EINVAL.

  authentication.

0513e13e31 Add a testcase which validates that the same buffer can be passed to
rijndael_blockDecrypt() as both input and output.

This property is important because inside rijndael we can get away
with allocating just a 16 byte "work" buffer on the stack (which
is very cheap), whereas the calling code would need to allocate the
full sized buffer, and in all likelyhood would have to do so with
an expensive malloc(9).
