db36b906fe Blackfin: Rename DES PC2() symbol to avoid collision
Rename the PC2() symbol in the generic DES crypto module to be prefixed with
DES_ to avoid collision with arch code (Blackfin in this case).

ad79cdd77f crypto: des3_ede - permit weak keys unless REQ_WEAK_KEY set
While its a slightly insane to bypass the key1 == key2 ||
key2 == key3 check in triple-des, since it reduces it to the
same strength as des, some folks do need to do this from time
to time for backwards compatibility with des.

My own case is FIPS CAVS test vectors. Many triple-des test
vectors use a single key, replicated 3x. In order to get the
expected results, des3_ede_setkey() needs to only reject weak
keys if the CRYPTO_TFM_REQ_WEAK_KEY flag is set.

Also sets a more appropriate RES flag when a weak key is found.

Thanks for the suggestion, the init() is replaced with

	<algorithm name>_mod_init ()

and fini () is replaced with <algorithm name>_mod_fini.

c5a511f1cd [CRYPTO] des: Rename des to des-generic
Loading the crypto algorithm by the alias instead of by module directly
has the advantage that all possible implementations of this algorithm
are loaded automatically and the crypto API can choose the best one
depending on its priority.
