I also needed this to actually test your vector.

BTW, please reformat your test vector so that it doesn't exceed
80 columns when you resubmit.

    crypto: testmgr - Allow hash test vectors longer than a page
    
    As it stands we will each test hash vector both linearly and as
    a scatter list if applicable.  This means that we cannot have
    vectors longer than a page, even with scatter lists.
    
    This patch fixes this by skipping test vectors with np != 0 when
    testing linearly.
