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

Before:	113MB/s
After:	203MB/s

BTW. If sector size is set to 128kB, I can read at 276MB/s :)

78c344f3da Modify PADLOCK_ALIGN() macro, so when the given address is already 16 bytes 
aligned, it will be used directly, not 'address + 16'.

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.
- Add support for the CRD_F_KEY_EXPLICIT flag, for both encryption and
  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).
