Message-ID: <20140518125615.2df48ea9@chukar.edge2.net>
Date: Sun, 18 May 2014 12:56:15 -0600

Subject: [PATCH v2 1/1] 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?).
Signed-off-by: Jake Edge <jake@....net>

Against next-20140516
v2: use git format-patch -M as suggested by Joe Perches
