[RFC PATCH 00/22] staging: add skein/threefish crypto algos

[Jason Cooper]

Greg, all,

Attached is a series I've sat on for the past month and a half.

I'm hoping that by posting it in it's incomplete state, it will either a)
motivate me to finish hooking into the crypto API, or b) motivate someone else
to pitch in. ;-)

>From patch 3, all commits build successfully.  In addition, using the script I
added in patch 1, I can confirm that no object code was harmed in this process.

I'm under no time crunch with this, and I add to it as I find time.  If Greg
wants to take it for v3.15, great.  Otherwise is fine as well.  It's been a
while since I watched the inner workings of the staging tree, so I'm not
familiar with how strict it is recently.

Barring a few false-positives, this series makes the code checkpatch-clean, but
it is not ready for mainline as yet.  In particular, I really don't like the
adhoc macro definitions, nor the camelCase.

The plan is to get skein and threefish registered into the crypto API, build as
modules, and then move it to crypto/.

To facilitate tinkering with this, One can pull from the following:

  git://git.infradead.org/users/jcooper/linux.git tags/staging-skein-3.14-rc1

This is based on v3.14-rc1, and is prone to rebasing based on comments.

thx,

Jason.
