    NFS: Change initial mount authflavor only when server returns NFS4ERR_WRONGSEC
    
    When attempting an initial mount, we should only attempt other
    authflavors if AUTH_UNIX receives a NFS4ERR_WRONGSEC error.
    This allows other errors to be passed back to userspace programs.

    NFS: Fix a signed vs. unsigned secinfo bug
    
    rpc_authflavor_t is cast from an unsigned int, but the
    initial code tried to use it as a signed int.  I fix
    this by passing an rpc_authflavor_t pointer around, and
    returning signed integers from functions.

    Revert "net/sunrpc: Use static const char arrays"
    
    This reverts commit 411b5e05617593efebc06241dbc56f42150f2abe.
    
    Olga Kornievskaia reports:
    
    Problem: linux client mounting linux server using rc4-hmac-md5
    enctype. gssd fails with create a context after receiving a reply from
    the server.
    
    Diagnose: putting printout statements in the server kernel and
    kerberos libraries revealed that client and server derived different
    integrity keys.
    
    Server kernel code was at fault due the the commit
    
    [aglo@skydive linux-pnfs]$ git show 411b5e05617593efebc06241dbc56f42150f2abe
    
    Trond: The problem is that since it relies on virt_to_page(), you cannot
    call sg_set_buf() for data in the const section.
