Sorry, only tested on x86-64 which doesn't have HIGHMEM.

I've just pushed the following fix into cryptodev-2.6.

commit 25531e010a2a1d0099b62d473244d09e72402ce5
Author: Herbert Xu <herbert@gondor.apana.org.au>
Date:   Sat Sep 1 16:52:13 2007 +0800

    [CRYPTO] api: Kill crypto_km_types

    When scatterwalk is built as a module digest.c was broken because it
    requires the crypto_km_types structure which is in scatterwalk.  This
    patch removes the crypto_km_types structure by encoding the logic into
    crypto_kmap_type directly.

    In fact, this even saves a few bytes of code (not to mention the data
    structure itself) on i386 which is about the only place where it's
    needed.
