James A Shackleford 7eb843aa50 staging: skein: fix sparse warning for static declarations
This patch fixes the following sparse warnings:

skein_block.c:43:6: warning: symbol 'skein_256_process_block' was not declared. Should it be static?
skein_block.c:252:6: warning: symbol 'skein_512_process_block' was not declared. Should it be static?
skein_block.c:483:6: warning: symbol 'skein_1024_process_block' was not declared. Should it be static?

by including the header skein_block.h, which contains the declarations in
question.

Jake Edge 85dfd522f8 staging/skein: rename files and clean up directory structure
Clean up file names and locations.  Get rid of include/ directory and move
those up to the top-level.  Rename files to get rid of upper case.  Remove
skeinBlockNo3F.c as it was unused (temporary file or something?).

Anton Saraev 0264b7b7fb staging: crypto: skein: rename macros
Mixing upper and lower case in names of macros like It_Is_Macro is
not accepted in the Linux Kernel. To prepare skein driver for mainline
inclusion, we rename all macros to uppercase or lowercase names.

Jason Cooper 6559e221a1 staging: crypto: skein: depend upon CRYPTO
Fengguang's randconfig kernel build tester discovered the following
warnings:

warning: (CRYPTO_THREEFISH) selects CRYPTO_ALGAPI which has unmet direct dependencies (CRYPTO)
warning: (DM_VERITY && CRYPTO_SKEIN) selects CRYPTO_HASH which has unmet direct dependencies (CRYPTO)

Fix this in the Kconfig by depending on CRYPTO.

Jason Cooper c2c7426bfc staging: crypto: skein: allow building statically
These are the minimum changes required to get the code to build
statically in the kernel.  It's necessary to do this first so that we
can empirically determine that future cleanup patches aren't changing
the generated object code.

Jason Cooper 449bb8125e staging: crypto: skein: import code from Skein3Fish.git
This is a byte-for-byte copy of the skein implementation found at:

  https://github.com/wernerd/Skein3Fish.git

Specifically, from the master branch at commit:

  00e925444c2c Merge pull request #4 from csm/master

The next commit will do the minimum necessary to build this code as a
module.
