Thanks. I have applied the following patch which I believe resolves
the problem. Cliff, could you test this?

commit 51438a32f6a0f09a358742f06196d14e4ad0ccab
Author: Simon Horman <horms at verge.net.au>
Date:   Wed Mar 13 10:48:48 2013 +0100

    Correct build failure in init_linux_parameters()
    
    This fixes a build failure introduced by
    "kexec x86: drop truncation warning for crash kernel".
