054c4a83dd 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 :)

90aa974bdf Modify PADLOCK_ALIGN() macro, so when the given address is already 16 bytes
aligned, it will be used directly, not 'address + 16'.

90eb685fca 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.

0495e43729 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.

4af607ffd5 Use the already stored VIA RNG probe information
instead of probing again.
Adjust style(9) somewhat in probe.c

87e654aa04 - 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.

a4071b836a padlock(4) doesn't support explicitly provided keys yet.
Return an error instead of encrypting/decrypting data with a wrong key.
