[RFC PATCH 00/30] crypto: DES/3DES cleanup

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

In my effort to remove crypto_alloc_cipher() invocations from non-crypto
code, i ran into a DES call in the CIFS driver. This is addressed in
patch #30.

The other patches are cleanups for the quirky DES interface, and lots
of duplication of the weak key checks etc.

Patch #1 adds new helpers to verify DES keys to crypto/internal.des.h

The next 23 patches move all existing users of DES routines to the
new interface.

Patch #25 and #26 are preparatory patches for the new DES library
introduced in patch #27, which replaces the various DES related
functions exported to other drivers with a sane library interface.

Patch #28 switches the x86 asm code to the new librar interface.

Patch #29 removes code that is no longer used at this point.
