This adds the module loading prefix "crypto-" to the template lookup
as well.For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly
includes the "crypto-" prefix at every level, correctly rejecting "vfat":net-pf-38

It turns out that LRW has never worked properly on big endian.
This was never discussed because nobody actually used it that
way. In fact, it was only discovered when Geert Uytterhoeven
loaded it through tcrypt which failed the test on it.The fix is straightforward, on big endian the to find the nth
bit we should be grouping them by words instead of bytes. So
setbit128_bbe should xor with 128 - BITS_PER_LONG instead of
128 - BITS_PER_BYTE == 0x78.Tested-by: Geert Uytterhoeven

Convert instances of ERR_PTR(PTR_ERR(p)) to ERR_CAST(p) using:
perl -spi -e 's/ERR_PTR[(]PTR_ERR[(](.*)[)][)]/ERR_CAST(\1)/' `grep -rl 'ERR_PTR[(]*PTR_ERR' fs crypto net security`

This patch passes the type/mask along when constructing instances of
templates. This is in preparation for templates that may support
multiple types of instances depending on what is requested. For example,
the planned software async crypto driver will use this construct.For the moment this allows us to check whether the instance constructed
is of the correct type and avoid returning success if the type does not
match.Signed-off-by: Herbert Xu

Main module, this implements the Liskov Rivest Wagner block cipher mode
in the new blockcipher API. The implementation is based on ecb.c.The LRW-32-AES specification I used can be found at:
http://grouper.ieee.org/groups/1619/email/pdf00017.pdfIt implements the optimization specified as optional in the
specification, and in addition it uses optimized multiplication
routines from gf128mul.c.Since gf128mul.[ch] is not tested on bigendian, this cipher mode
may currently fail badly on bigendian machines.Signed-off-by: Rik Snel
